Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515682, here are decompositions:

5 + 31515677 = 31515682
41 + 31515641 = 31515682
53 + 31515629 = 31515682
71 + 31515611 = 31515682
83 + 31515599 = 31515682
269 + 31515413 = 31515682
281 + 31515401 = 31515682
293 + 31515389 = 31515682

Showing the first eight; more decompositions exist.
