Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537824, here are decompositions:
- 83 + 31537741 = 31537824
- 103 + 31537721 = 31537824
- 107 + 31537717 = 31537824
- 137 + 31537687 = 31537824
- 193 + 31537631 = 31537824
- 233 + 31537591 = 31537824
- 251 + 31537573 = 31537824
- 277 + 31537547 = 31537824
Showing the first eight; more decompositions exist.
