Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458928, here are decompositions:
- 5 + 31458923 = 31458928
- 107 + 31458821 = 31458928
- 131 + 31458797 = 31458928
- 167 + 31458761 = 31458928
- 227 + 31458701 = 31458928
- 239 + 31458689 = 31458928
- 401 + 31458527 = 31458928
- 491 + 31458437 = 31458928
Showing the first eight; more decompositions exist.
