Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537352, here are decompositions:
- 13 + 31537339 = 31537352
- 43 + 31537309 = 31537352
- 79 + 31537273 = 31537352
- 109 + 31537243 = 31537352
- 151 + 31537201 = 31537352
- 199 + 31537153 = 31537352
- 313 + 31537039 = 31537352
- 349 + 31537003 = 31537352
Showing the first eight; more decompositions exist.
