Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7656, here are decompositions:
- 7 + 7649 = 7656
- 13 + 7643 = 7656
- 17 + 7639 = 7656
- 53 + 7603 = 7656
- 67 + 7589 = 7656
- 73 + 7583 = 7656
- 79 + 7577 = 7656
- 83 + 7573 = 7656
Showing the first eight; more decompositions exist.
