Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537764, here are decompositions:
- 17 + 31537747 = 31537764
- 23 + 31537741 = 31537764
- 43 + 31537721 = 31537764
- 47 + 31537717 = 31537764
- 73 + 31537691 = 31537764
- 173 + 31537591 = 31537764
- 191 + 31537573 = 31537764
- 257 + 31537507 = 31537764
Showing the first eight; more decompositions exist.
