Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476682, here are decompositions:

59 + 31476623 = 31476682
71 + 31476611 = 31476682
89 + 31476593 = 31476682
131 + 31476551 = 31476682
173 + 31476509 = 31476682
233 + 31476449 = 31476682
269 + 31476413 = 31476682
311 + 31476371 = 31476682

Showing the first eight; more decompositions exist.
