It is: 61+67+71+73+79+83+89+97 = 620
61 and 3
61, 37 89, 7, 2
For a 2-digit prime number (which are all odd) to be the sum of two prime numbers, one of the prime numbers will have to be 2. That means the difference between the sum and the other addend will have to be 2. Prime numbers that differ by 2 are called twin primes. There are six pairs of 2-digit twin primes. Your numbers are 13, 19, 31, 43, 61 and 73.
ANSWER: 311First five prime numbers after 50: 53, 59, 61, 67, 71Sum = 53 + 59 + 61 + 67 + 71 = 311
Including 61 and 97 the sum is 620
There is only one and it is 61 and so 61+0 = 61
The sum is: 61+67+71+73+79+83+89 = 523
The prime numbers are: 53 59 61 67 71 73 79 83 89 97 The sum is: 732
It is: 61+67+71+73+79+83+89+97 = 620
37 and 61 are two prime numbers having the sum of 98.
61 and 3
The sum is: 61+67+71+73+79+83+89+97 = 620
61 + 67 + 71 + 73 + 79 = 351
3 and 61 is one possible answer.
The sum of the prime numbers 2, 5, and 61 is 68.
It is: 61+67+71+73+79+83+89+97 = 620
