Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545876, here are decompositions:
- 17 + 31545859 = 31545876
- 113 + 31545763 = 31545876
- 127 + 31545749 = 31545876
- 137 + 31545739 = 31545876
- 139 + 31545737 = 31545876
- 163 + 31545713 = 31545876
- 269 + 31545607 = 31545876
- 277 + 31545599 = 31545876
Showing the first eight; more decompositions exist.
