Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68508, here are decompositions:
- 7 + 68501 = 68508
- 17 + 68491 = 68508
- 19 + 68489 = 68508
- 31 + 68477 = 68508
- 59 + 68449 = 68508
- 61 + 68447 = 68508
- 71 + 68437 = 68508
- 109 + 68399 = 68508
Showing the first eight; more decompositions exist.
