Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461686, here are decompositions:
- 13 + 31461673 = 31461686
- 163 + 31461523 = 31461686
- 199 + 31461487 = 31461686
- 229 + 31461457 = 31461686
- 283 + 31461403 = 31461686
- 337 + 31461349 = 31461686
- 433 + 31461253 = 31461686
- 457 + 31461229 = 31461686
Showing the first eight; more decompositions exist.
