Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537770, here are decompositions:
- 23 + 31537747 = 31537770
- 29 + 31537741 = 31537770
- 53 + 31537717 = 31537770
- 79 + 31537691 = 31537770
- 83 + 31537687 = 31537770
- 139 + 31537631 = 31537770
- 167 + 31537603 = 31537770
- 179 + 31537591 = 31537770
Showing the first eight; more decompositions exist.
