Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517134, here are decompositions:

71 + 31517063 = 31517134
107 + 31517027 = 31517134
113 + 31517021 = 31517134
293 + 31516841 = 31517134
347 + 31516787 = 31517134
353 + 31516781 = 31517134
431 + 31516703 = 31517134
503 + 31516631 = 31517134

Showing the first eight; more decompositions exist.
