Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518412, here are decompositions:
- 59 + 31518353 = 31518412
- 83 + 31518329 = 31518412
- 131 + 31518281 = 31518412
- 173 + 31518239 = 31518412
- 239 + 31518173 = 31518412
- 389 + 31518023 = 31518412
- 449 + 31517963 = 31518412
- 461 + 31517951 = 31518412
Showing the first eight; more decompositions exist.
