Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613936, here are decompositions:
- 97 + 31613839 = 31613936
- 103 + 31613833 = 31613936
- 139 + 31613797 = 31613936
- 307 + 31613629 = 31613936
- 313 + 31613623 = 31613936
- 397 + 31613539 = 31613936
- 499 + 31613437 = 31613936
- 709 + 31613227 = 31613936
Showing the first eight; more decompositions exist.
