Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486476, here are decompositions:

13 + 31486463 = 31486476
19 + 31486457 = 31486476
23 + 31486453 = 31486476
53 + 31486423 = 31486476
59 + 31486417 = 31486476
83 + 31486393 = 31486476
89 + 31486387 = 31486476
127 + 31486349 = 31486476

Showing the first eight; more decompositions exist.
