Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537616, here are decompositions:
- 7 + 31537609 = 31537616
- 13 + 31537603 = 31537616
- 43 + 31537573 = 31537616
- 73 + 31537543 = 31537616
- 109 + 31537507 = 31537616
- 139 + 31537477 = 31537616
- 277 + 31537339 = 31537616
- 307 + 31537309 = 31537616
Showing the first eight; more decompositions exist.
