Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545884, here are decompositions:
- 43 + 31545841 = 31545884
- 277 + 31545607 = 31545884
- 397 + 31545487 = 31545884
- 541 + 31545343 = 31545884
- 673 + 31545211 = 31545884
- 787 + 31545097 = 31545884
- 823 + 31545061 = 31545884
- 883 + 31545001 = 31545884
Showing the first eight; more decompositions exist.
