Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586930, here are decompositions:
- 3 + 31586927 = 31586930
- 61 + 31586869 = 31586930
- 127 + 31586803 = 31586930
- 139 + 31586791 = 31586930
- 211 + 31586719 = 31586930
- 223 + 31586707 = 31586930
- 241 + 31586689 = 31586930
- 283 + 31586647 = 31586930
Showing the first eight; more decompositions exist.
