Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537368, here are decompositions:
- 29 + 31537339 = 31537368
- 41 + 31537327 = 31537368
- 59 + 31537309 = 31537368
- 61 + 31537307 = 31537368
- 97 + 31537271 = 31537368
- 101 + 31537267 = 31537368
- 139 + 31537229 = 31537368
- 167 + 31537201 = 31537368
Showing the first eight; more decompositions exist.
