Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78656, here are decompositions:
- 3 + 78653 = 78656
- 7 + 78649 = 78656
- 13 + 78643 = 78656
- 73 + 78583 = 78656
- 79 + 78577 = 78656
- 103 + 78553 = 78656
- 139 + 78517 = 78656
- 229 + 78427 = 78656
Showing the first eight; more decompositions exist.
