Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517714, here are decompositions:

13 + 31517701 = 31517714
61 + 31517653 = 31517714
73 + 31517641 = 31517714
97 + 31517617 = 31517714
127 + 31517587 = 31517714
157 + 31517557 = 31517714
181 + 31517533 = 31517714
223 + 31517491 = 31517714

Showing the first eight; more decompositions exist.
