Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12608, here are decompositions:
- 7 + 12601 = 12608
- 19 + 12589 = 12608
- 31 + 12577 = 12608
- 61 + 12547 = 12608
- 67 + 12541 = 12608
- 97 + 12511 = 12608
- 151 + 12457 = 12608
- 157 + 12451 = 12608
Showing the first eight; more decompositions exist.
