Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624232, here are decompositions:
- 103 + 31624129 = 31624232
- 163 + 31624069 = 31624232
- 229 + 31624003 = 31624232
- 331 + 31623901 = 31624232
- 643 + 31623589 = 31624232
- 709 + 31623523 = 31624232
- 733 + 31623499 = 31624232
- 751 + 31623481 = 31624232
Showing the first eight; more decompositions exist.
