Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517996, here are decompositions:

43 + 31517953 = 31517996
109 + 31517887 = 31517996
379 + 31517617 = 31517996
409 + 31517587 = 31517996
439 + 31517557 = 31517996
463 + 31517533 = 31517996
607 + 31517389 = 31517996
1117 + 31516879 = 31517996

Showing the first eight; more decompositions exist.
