Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537110, here are decompositions:
- 13 + 31537097 = 31537110
- 23 + 31537087 = 31537110
- 61 + 31537049 = 31537110
- 67 + 31537043 = 31537110
- 71 + 31537039 = 31537110
- 83 + 31537027 = 31537110
- 107 + 31537003 = 31537110
- 109 + 31537001 = 31537110
Showing the first eight; more decompositions exist.
