Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517076, here are decompositions:

13 + 31517063 = 31517076
37 + 31517039 = 31517076
83 + 31516993 = 31517076
103 + 31516973 = 31517076
197 + 31516879 = 31517076
257 + 31516819 = 31517076
347 + 31516729 = 31517076
373 + 31516703 = 31517076

Showing the first eight; more decompositions exist.
