Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537790, here are decompositions:
- 43 + 31537747 = 31537790
- 73 + 31537717 = 31537790
- 103 + 31537687 = 31537790
- 181 + 31537609 = 31537790
- 199 + 31537591 = 31537790
- 283 + 31537507 = 31537790
- 313 + 31537477 = 31537790
- 463 + 31537327 = 31537790
Showing the first eight; more decompositions exist.
