Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540644, here are decompositions:
- 7 + 31540637 = 31540644
- 13 + 31540631 = 31540644
- 71 + 31540573 = 31540644
- 151 + 31540493 = 31540644
- 173 + 31540471 = 31540644
- 227 + 31540417 = 31540644
- 281 + 31540363 = 31540644
- 347 + 31540297 = 31540644
Showing the first eight; more decompositions exist.
