Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609512, here are decompositions:
- 13 + 31609499 = 31609512
- 19 + 31609493 = 31609512
- 31 + 31609481 = 31609512
- 43 + 31609469 = 31609512
- 59 + 31609453 = 31609512
- 61 + 31609451 = 31609512
- 131 + 31609381 = 31609512
- 173 + 31609339 = 31609512
Showing the first eight; more decompositions exist.
