Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518064, here are decompositions:

3 + 31518061 = 31518064
41 + 31518023 = 31518064
101 + 31517963 = 31518064
113 + 31517951 = 31518064
467 + 31517597 = 31518064
491 + 31517573 = 31518064
521 + 31517543 = 31518064
563 + 31517501 = 31518064

Showing the first eight; more decompositions exist.
