Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10688, here are decompositions:
- 31 + 10657 = 10688
- 37 + 10651 = 10688
- 61 + 10627 = 10688
- 157 + 10531 = 10688
- 211 + 10477 = 10688
- 229 + 10459 = 10688
- 331 + 10357 = 10688
- 367 + 10321 = 10688
Showing the first eight; more decompositions exist.
