Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68340, here are decompositions:
- 11 + 68329 = 68340
- 29 + 68311 = 68340
- 59 + 68281 = 68340
- 61 + 68279 = 68340
- 79 + 68261 = 68340
- 101 + 68239 = 68340
- 113 + 68227 = 68340
- 127 + 68213 = 68340
Showing the first eight; more decompositions exist.
