Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27688, here are decompositions:
- 41 + 27647 = 27688
- 71 + 27617 = 27688
- 107 + 27581 = 27688
- 137 + 27551 = 27688
- 149 + 27539 = 27688
- 179 + 27509 = 27688
- 239 + 27449 = 27688
- 251 + 27437 = 27688
Showing the first eight; more decompositions exist.
