Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536984, here are decompositions:
- 41 + 31536943 = 31536984
- 47 + 31536937 = 31536984
- 67 + 31536917 = 31536984
- 113 + 31536871 = 31536984
- 137 + 31536847 = 31536984
- 163 + 31536821 = 31536984
- 191 + 31536793 = 31536984
- 211 + 31536773 = 31536984
Showing the first eight; more decompositions exist.
