Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537662, here are decompositions:
- 31 + 31537631 = 31537662
- 53 + 31537609 = 31537662
- 59 + 31537603 = 31537662
- 71 + 31537591 = 31537662
- 89 + 31537573 = 31537662
- 103 + 31537559 = 31537662
- 181 + 31537481 = 31537662
- 193 + 31537469 = 31537662
Showing the first eight; more decompositions exist.
