Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624016, here are decompositions:
- 3 + 31624013 = 31624016
- 13 + 31624003 = 31624016
- 37 + 31623979 = 31624016
- 199 + 31623817 = 31624016
- 313 + 31623703 = 31624016
- 349 + 31623667 = 31624016
- 409 + 31623607 = 31624016
- 577 + 31623439 = 31624016
Showing the first eight; more decompositions exist.
