Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497512, here are decompositions:
- 43 + 31497469 = 31497512
- 103 + 31497409 = 31497512
- 199 + 31497313 = 31497512
- 229 + 31497283 = 31497512
- 283 + 31497229 = 31497512
- 373 + 31497139 = 31497512
- 379 + 31497133 = 31497512
- 523 + 31496989 = 31497512
Showing the first eight; more decompositions exist.
