Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517616, here are decompositions:

19 + 31517597 = 31517616
29 + 31517587 = 31517616
37 + 31517579 = 31517616
43 + 31517573 = 31517616
59 + 31517557 = 31517616
73 + 31517543 = 31517616
83 + 31517533 = 31517616
89 + 31517527 = 31517616

Showing the first eight; more decompositions exist.
