Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545416, here are decompositions:
- 37 + 31545379 = 31545416
- 43 + 31545373 = 31545416
- 73 + 31545343 = 31545416
- 349 + 31545067 = 31545416
- 367 + 31545049 = 31545416
- 829 + 31544587 = 31545416
- 883 + 31544533 = 31545416
- 907 + 31544509 = 31545416
Showing the first eight; more decompositions exist.
