Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560958, here are decompositions:
- 17 + 31560941 = 31560958
- 47 + 31560911 = 31560958
- 71 + 31560887 = 31560958
- 89 + 31560869 = 31560958
- 167 + 31560791 = 31560958
- 227 + 31560731 = 31560958
- 239 + 31560719 = 31560958
- 269 + 31560689 = 31560958
Showing the first eight; more decompositions exist.
