Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537590, here are decompositions:
- 17 + 31537573 = 31537590
- 31 + 31537559 = 31537590
- 43 + 31537547 = 31537590
- 47 + 31537543 = 31537590
- 83 + 31537507 = 31537590
- 109 + 31537481 = 31537590
- 113 + 31537477 = 31537590
- 157 + 31537433 = 31537590
Showing the first eight; more decompositions exist.
