Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544638, here are decompositions:
- 107 + 31544531 = 31544638
- 431 + 31544207 = 31544638
- 449 + 31544189 = 31544638
- 467 + 31544171 = 31544638
- 599 + 31544039 = 31544638
- 617 + 31544021 = 31544638
- 641 + 31543997 = 31544638
- 647 + 31543991 = 31544638
Showing the first eight; more decompositions exist.
