Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623710, here are decompositions:
- 3 + 31623707 = 31623710
- 7 + 31623703 = 31623710
- 43 + 31623667 = 31623710
- 103 + 31623607 = 31623710
- 199 + 31623511 = 31623710
- 211 + 31623499 = 31623710
- 229 + 31623481 = 31623710
- 271 + 31623439 = 31623710
Showing the first eight; more decompositions exist.
