Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545992, here are decompositions:
- 73 + 31545919 = 31545992
- 151 + 31545841 = 31545992
- 229 + 31545763 = 31545992
- 523 + 31545469 = 31545992
- 601 + 31545391 = 31545992
- 613 + 31545379 = 31545992
- 619 + 31545373 = 31545992
- 661 + 31545331 = 31545992
Showing the first eight; more decompositions exist.
