Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537656, here are decompositions:
- 47 + 31537609 = 31537656
- 53 + 31537603 = 31537656
- 83 + 31537573 = 31537656
- 97 + 31537559 = 31537656
- 109 + 31537547 = 31537656
- 113 + 31537543 = 31537656
- 149 + 31537507 = 31537656
- 179 + 31537477 = 31537656
Showing the first eight; more decompositions exist.
