Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609932, here are decompositions:
- 61 + 31609871 = 31609932
- 71 + 31609861 = 31609932
- 83 + 31609849 = 31609932
- 113 + 31609819 = 31609932
- 139 + 31609793 = 31609932
- 163 + 31609769 = 31609932
- 173 + 31609759 = 31609932
- 191 + 31609741 = 31609932
Showing the first eight; more decompositions exist.
