Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602512, here are decompositions:
- 31 + 31602481 = 31602512
- 61 + 31602451 = 31602512
- 349 + 31602163 = 31602512
- 433 + 31602079 = 31602512
- 463 + 31602049 = 31602512
- 631 + 31601881 = 31602512
- 769 + 31601743 = 31602512
- 883 + 31601629 = 31602512
Showing the first eight; more decompositions exist.
