Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537692, here are decompositions:
- 5 + 31537687 = 31537692
- 61 + 31537631 = 31537692
- 83 + 31537609 = 31537692
- 89 + 31537603 = 31537692
- 101 + 31537591 = 31537692
- 149 + 31537543 = 31537692
- 211 + 31537481 = 31537692
- 223 + 31537469 = 31537692
Showing the first eight; more decompositions exist.
