Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535966, here are decompositions:
- 19 + 31535947 = 31535966
- 139 + 31535827 = 31535966
- 157 + 31535809 = 31535966
- 373 + 31535593 = 31535966
- 463 + 31535503 = 31535966
- 499 + 31535467 = 31535966
- 547 + 31535419 = 31535966
- 733 + 31535233 = 31535966
Showing the first eight; more decompositions exist.
