Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545860, here are decompositions:
- 19 + 31545841 = 31545860
- 97 + 31545763 = 31545860
- 193 + 31545667 = 31545860
- 373 + 31545487 = 31545860
- 421 + 31545439 = 31545860
- 487 + 31545373 = 31545860
- 769 + 31545091 = 31545860
- 811 + 31545049 = 31545860
Showing the first eight; more decompositions exist.
