Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517052, here are decompositions:

13 + 31517039 = 31517052
31 + 31517021 = 31517052
41 + 31517011 = 31517052
59 + 31516993 = 31517052
71 + 31516981 = 31517052
79 + 31516973 = 31517052
101 + 31516951 = 31517052
163 + 31516889 = 31517052

Showing the first eight; more decompositions exist.
