Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517176, here are decompositions:

113 + 31517063 = 31517176
137 + 31517039 = 31517176
149 + 31517027 = 31517176
389 + 31516787 = 31517176
419 + 31516757 = 31517176
479 + 31516697 = 31517176
557 + 31516619 = 31517176
563 + 31516613 = 31517176

Showing the first eight; more decompositions exist.
