Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545746, here are decompositions:
- 3 + 31545743 = 31545746
- 7 + 31545739 = 31545746
- 79 + 31545667 = 31545746
- 139 + 31545607 = 31545746
- 277 + 31545469 = 31545746
- 307 + 31545439 = 31545746
- 367 + 31545379 = 31545746
- 373 + 31545373 = 31545746
Showing the first eight; more decompositions exist.
