There are an infinite number of square numbers and prime numbers whose sums are a prime number. Examples are 202 + 103 = 503, 22 + 13 = 17, 102 + 601 = 701, 22 + 163 = 167, 42 + 141 = 157, etc.
The prime numbers up to 50 are: 2,3,5,7,11,13,17,23,29,31,37,41,43,47.
Prime numbers are those numbers which are only divisible by itself Likewise, 1,3,5,7,11,13,17,19,23,,29,31,37,41,43,47,51,53,57,59. These are the only prime numbers upto 60.
There are no prime numbers greater than 10 that add up to 29. Since all prime numbers greater than 2 are odd numbers, no two prime numbers greater than 2 can have an even number for their sum.
The quoted numbers are all PRIME Numbers. The next prime numbers after '11' are , 13 ,17,19,23,29,31,37,41,43,47, up to '50' Prime Numbers , like ordinary numbers, go to infinity. NB After '2' , there are no. even prime numbers. They are all ODD NUmbers.

There are an infinite number of square numbers and prime numbers whose sums are a prime number. Examples are 202 + 103 = 503, 22 + 13 = 17, 102 + 601 = 701, 22 + 163 = 167, 42 + 141 = 157, etc.
There is an infinite number of prime numbers after 500!
The odd numbers are 101, 103, 105, 107, 109, etc. - just add two at a time. To include only composite numbers, look up a table of prime numbers, and delete those from the list.
The prime numbers up to 50 are: 2,3,5,7,11,13,17,23,29,31,37,41,43,47.
Prime numbers are those numbers which are only divisible by itself Likewise, 1,3,5,7,11,13,17,19,23,,29,31,37,41,43,47,51,53,57,59. These are the only prime numbers upto 60.
So the composite numbers won't get all bunched up.
2,3,5,7,11,13,17,19,23,29,31,37,39,41,43,47,51,53,57,59,61,67,71,73
There are no prime numbers greater than 10 that add up to 29. Since all prime numbers greater than 2 are odd numbers, no two prime numbers greater than 2 can have an even number for their sum.
Look up a table of prime numbers. All those numbers that are not prime, are composite - except 1, which is neither prime nor composite.
The two prime numbers that add up to 247 are 241 and 6. 241 is a prime number because it has only two factors: 1 and 241. However, 6 is not a prime number because it has more than two factors: 1, 2, 3, and 6. When you add 241 and 6 together, you get 247.
The quoted numbers are all PRIME Numbers. The next prime numbers after '11' are , 13 ,17,19,23,29,31,37,41,43,47, up to '50' Prime Numbers , like ordinary numbers, go to infinity. NB After '2' , there are no. even prime numbers. They are all ODD NUmbers.
