Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516610, here are decompositions:

7 + 31516603 = 31516610
43 + 31516567 = 31516610
67 + 31516543 = 31516610
109 + 31516501 = 31516610
127 + 31516483 = 31516610
199 + 31516411 = 31516610
277 + 31516333 = 31516610
283 + 31516327 = 31516610

Showing the first eight; more decompositions exist.
