Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512422, here are decompositions:
- 13 + 31512409 = 31512422
- 79 + 31512343 = 31512422
- 163 + 31512259 = 31512422
- 211 + 31512211 = 31512422
- 223 + 31512199 = 31512422
- 313 + 31512109 = 31512422
- 541 + 31511881 = 31512422
- 619 + 31511803 = 31512422
Showing the first eight; more decompositions exist.
