Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537948, here are decompositions:
- 59 + 31537889 = 31537948
- 89 + 31537859 = 31537948
- 227 + 31537721 = 31537948
- 257 + 31537691 = 31537948
- 317 + 31537631 = 31537948
- 389 + 31537559 = 31537948
- 401 + 31537547 = 31537948
- 467 + 31537481 = 31537948
Showing the first eight; more decompositions exist.
