Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536570, here are decompositions:
- 19 + 31536551 = 31536570
- 31 + 31536539 = 31536570
- 41 + 31536529 = 31536570
- 71 + 31536499 = 31536570
- 89 + 31536481 = 31536570
- 167 + 31536403 = 31536570
- 173 + 31536397 = 31536570
- 179 + 31536391 = 31536570
Showing the first eight; more decompositions exist.
