Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537860, here are decompositions:
- 17 + 31537843 = 31537860
- 23 + 31537837 = 31537860
- 37 + 31537823 = 31537860
- 113 + 31537747 = 31537860
- 139 + 31537721 = 31537860
- 173 + 31537687 = 31537860
- 229 + 31537631 = 31537860
- 251 + 31537609 = 31537860
Showing the first eight; more decompositions exist.
