Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537748, here are decompositions:
- 7 + 31537741 = 31537748
- 31 + 31537717 = 31537748
- 61 + 31537687 = 31537748
- 139 + 31537609 = 31537748
- 157 + 31537591 = 31537748
- 241 + 31537507 = 31537748
- 271 + 31537477 = 31537748
- 409 + 31537339 = 31537748
Showing the first eight; more decompositions exist.
