Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512412, here are decompositions:
- 3 + 31512409 = 31512412
- 53 + 31512359 = 31512412
- 251 + 31512161 = 31512412
- 293 + 31512119 = 31512412
- 353 + 31512059 = 31512412
- 389 + 31512023 = 31512412
- 401 + 31512011 = 31512412
- 419 + 31511993 = 31512412
Showing the first eight; more decompositions exist.
