Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535908, here are decompositions:
- 29 + 31535879 = 31535908
- 167 + 31535741 = 31535908
- 191 + 31535717 = 31535908
- 227 + 31535681 = 31535908
- 251 + 31535657 = 31535908
- 269 + 31535639 = 31535908
- 317 + 31535591 = 31535908
- 359 + 31535549 = 31535908
Showing the first eight; more decompositions exist.
