Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68518, here are decompositions:
- 11 + 68507 = 68518
- 17 + 68501 = 68518
- 29 + 68489 = 68518
- 41 + 68477 = 68518
- 71 + 68447 = 68518
- 167 + 68351 = 68518
- 239 + 68279 = 68518
- 257 + 68261 = 68518
Showing the first eight; more decompositions exist.
