Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523610, here are decompositions:
- 11 + 31523599 = 31523610
- 31 + 31523579 = 31523610
- 71 + 31523539 = 31523610
- 73 + 31523537 = 31523610
- 89 + 31523521 = 31523610
- 137 + 31523473 = 31523610
- 149 + 31523461 = 31523610
- 191 + 31523419 = 31523610
Showing the first eight; more decompositions exist.
