Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545862, here are decompositions:
- 3 + 31545859 = 31545862
- 113 + 31545749 = 31545862
- 149 + 31545713 = 31545862
- 233 + 31545629 = 31545862
- 239 + 31545623 = 31545862
- 251 + 31545611 = 31545862
- 263 + 31545599 = 31545862
- 461 + 31545401 = 31545862
Showing the first eight; more decompositions exist.
