Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541598, here are decompositions:
- 7 + 31541591 = 31541598
- 17 + 31541581 = 31541598
- 29 + 31541569 = 31541598
- 41 + 31541557 = 31541598
- 71 + 31541527 = 31541598
- 89 + 31541509 = 31541598
- 131 + 31541467 = 31541598
- 149 + 31541449 = 31541598
Showing the first eight; more decompositions exist.
