Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512962, here are decompositions:
- 3 + 31512959 = 31512962
- 139 + 31512823 = 31512962
- 193 + 31512769 = 31512962
- 223 + 31512739 = 31512962
- 331 + 31512631 = 31512962
- 463 + 31512499 = 31512962
- 619 + 31512343 = 31512962
- 631 + 31512331 = 31512962
Showing the first eight; more decompositions exist.
