Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517684, here are decompositions:

31 + 31517653 = 31517684
43 + 31517641 = 31517684
67 + 31517617 = 31517684
97 + 31517587 = 31517684
127 + 31517557 = 31517684
151 + 31517533 = 31517684
157 + 31517527 = 31517684
193 + 31517491 = 31517684

Showing the first eight; more decompositions exist.
