Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537758, here are decompositions:
- 11 + 31537747 = 31537758
- 17 + 31537741 = 31537758
- 37 + 31537721 = 31537758
- 41 + 31537717 = 31537758
- 67 + 31537691 = 31537758
- 71 + 31537687 = 31537758
- 127 + 31537631 = 31537758
- 149 + 31537609 = 31537758
Showing the first eight; more decompositions exist.
