Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545966, here are decompositions:
- 7 + 31545959 = 31545966
- 13 + 31545953 = 31545966
- 43 + 31545923 = 31545966
- 47 + 31545919 = 31545966
- 79 + 31545887 = 31545966
- 107 + 31545859 = 31545966
- 223 + 31545743 = 31545966
- 227 + 31545739 = 31545966
Showing the first eight; more decompositions exist.
