Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512734, here are decompositions:
- 3 + 31512731 = 31512734
- 31 + 31512703 = 31512734
- 61 + 31512673 = 31512734
- 103 + 31512631 = 31512734
- 283 + 31512451 = 31512734
- 523 + 31512211 = 31512734
- 613 + 31512121 = 31512734
- 853 + 31511881 = 31512734
Showing the first eight; more decompositions exist.
