Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615828, here are decompositions:
- 71 + 31615757 = 31615828
- 239 + 31615589 = 31615828
- 389 + 31615439 = 31615828
- 599 + 31615229 = 31615828
- 617 + 31615211 = 31615828
- 641 + 31615187 = 31615828
- 659 + 31615169 = 31615828
- 701 + 31615127 = 31615828
Showing the first eight; more decompositions exist.
