Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518712, here are decompositions:
- 53 + 31518659 = 31518712
- 59 + 31518653 = 31518712
- 191 + 31518521 = 31518712
- 359 + 31518353 = 31518712
- 383 + 31518329 = 31518712
- 431 + 31518281 = 31518712
- 503 + 31518209 = 31518712
- 761 + 31517951 = 31518712
Showing the first eight; more decompositions exist.
