Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509632, here are decompositions:
- 3 + 31509629 = 31509632
- 31 + 31509601 = 31509632
- 61 + 31509571 = 31509632
- 79 + 31509553 = 31509632
- 103 + 31509529 = 31509632
- 109 + 31509523 = 31509632
- 163 + 31509469 = 31509632
- 199 + 31509433 = 31509632
Showing the first eight; more decompositions exist.
