Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537682, here are decompositions:
- 73 + 31537609 = 31537682
- 79 + 31537603 = 31537682
- 109 + 31537573 = 31537682
- 139 + 31537543 = 31537682
- 373 + 31537309 = 31537682
- 409 + 31537273 = 31537682
- 439 + 31537243 = 31537682
- 643 + 31537039 = 31537682
Showing the first eight; more decompositions exist.
