Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535608, here are decompositions:
- 17 + 31535591 = 31535608
- 59 + 31535549 = 31535608
- 179 + 31535429 = 31535608
- 191 + 31535417 = 31535608
- 197 + 31535411 = 31535608
- 227 + 31535381 = 31535608
- 281 + 31535327 = 31535608
- 389 + 31535219 = 31535608
Showing the first eight; more decompositions exist.
