Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536708, here are decompositions:
- 11 + 31536697 = 31536708
- 79 + 31536629 = 31536708
- 101 + 31536607 = 31536708
- 157 + 31536551 = 31536708
- 179 + 31536529 = 31536708
- 227 + 31536481 = 31536708
- 311 + 31536397 = 31536708
- 317 + 31536391 = 31536708
Showing the first eight; more decompositions exist.
