Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545996, here are decompositions:
- 5 + 31545991 = 31545996
- 37 + 31545959 = 31545996
- 43 + 31545953 = 31545996
- 73 + 31545923 = 31545996
- 109 + 31545887 = 31545996
- 137 + 31545859 = 31545996
- 233 + 31545763 = 31545996
- 257 + 31545739 = 31545996
Showing the first eight; more decompositions exist.
