Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516682, here are decompositions:

13 + 31516669 = 31516682
79 + 31516603 = 31516682
139 + 31516543 = 31516682
163 + 31516519 = 31516682
181 + 31516501 = 31516682
199 + 31516483 = 31516682
271 + 31516411 = 31516682
349 + 31516333 = 31516682

Showing the first eight; more decompositions exist.
