Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517796, here are decompositions:

47 + 31517749 = 31517796
67 + 31517729 = 31517796
73 + 31517723 = 31517796
97 + 31517699 = 31517796
157 + 31517639 = 31517796
179 + 31517617 = 31517796
199 + 31517597 = 31517796
223 + 31517573 = 31517796

Showing the first eight; more decompositions exist.
