Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541610, here are decompositions:
- 13 + 31541597 = 31541610
- 19 + 31541591 = 31541610
- 29 + 31541581 = 31541610
- 41 + 31541569 = 31541610
- 47 + 31541563 = 31541610
- 53 + 31541557 = 31541610
- 83 + 31541527 = 31541610
- 101 + 31541509 = 31541610
Showing the first eight; more decompositions exist.
