Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517062, here are decompositions:

23 + 31517039 = 31517062
41 + 31517021 = 31517062
89 + 31516973 = 31517062
173 + 31516889 = 31517062
251 + 31516811 = 31517062
281 + 31516781 = 31517062
359 + 31516703 = 31517062
431 + 31516631 = 31517062

Showing the first eight; more decompositions exist.
