Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492482, here are decompositions:

5 + 31492477 = 31492482
11 + 31492471 = 31492482
29 + 31492453 = 31492482
53 + 31492429 = 31492482
59 + 31492423 = 31492482
61 + 31492421 = 31492482
79 + 31492403 = 31492482
83 + 31492399 = 31492482

Showing the first eight; more decompositions exist.
