The prime numbers 3 an 7 are both odd and sum to 10.
There are not three odd primes with the sum of 14. The sum of three odd primes will be an odd number.
Sure. All composite numbers can be written as a product of primes. It shouldn't be tough to find a composite number that's the sum of three other composite numbers. Let's try 30. 2 x 3 x 5 = 30 Product of primes, check. 6 (2 x 3) + 10 (2 x 5) + 14 (2 x 7) = 30 Sum of three products of primes, check.
This question cannot be answered because three odd primes always have an odd number for their sum.
Goldbach's conjecture: Every even integer n greater than two is the sum of two primes see below for the reference
It is: 2+3+5+7 = 17
1, 2, 3, 5, 7 are the primes under 10. Those add up to 18.
The prime numbers 3 an 7 are both odd and sum to 10.
10
All prime numbers greater than 2 are odd numbers. For an odd prime to be written as the sum of two primes, one of the primes must be 2 because two odd primes will produce an even sum. 11 cannot be written as the sum of two primes. 13 = 2 + 11. 17 cannot be written as the sum of two primes. 19 = 2 + 17.
There are not three odd primes with the sum of 14. The sum of three odd primes will be an odd number.
Are you asking The first prime that is the sum of three primes? I'll help. 2,3,5 are the first 3. the sum is 10. Not prime. now try 3,5,7. 15. Not prime. 5,7,11. 5,7,11 work, the sum is 23, which is a prime, not divisible by 2,3,4,5,6,7,8,9, so on. So the Three Primes are 5 7 11. The sum is 23.
Infinity.
Not true. 2 + 3 = 5, where all three are primes. One of the primes in the sum must be 2, otherwise both primes would be odd and their sum would be even (and >2) and therefore not prime. Such primes: p and p+2 [3 and 5 in the above example] are known as twin primes and there are infiitely many twin primes.
Sure. All composite numbers can be written as a product of primes. It shouldn't be tough to find a composite number that's the sum of three other composite numbers. Let's try 30. 2 x 3 x 5 = 30 Product of primes, check. 6 (2 x 3) + 10 (2 x 5) + 14 (2 x 7) = 30 Sum of three products of primes, check.
The twin primes 41 + 43 = 84.
This question cannot be answered because three odd primes always have an odd number for their sum.
