Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476676, here are decompositions:

53 + 31476623 = 31476676
83 + 31476593 = 31476676
89 + 31476587 = 31476676
167 + 31476509 = 31476676
227 + 31476449 = 31476676
239 + 31476437 = 31476676
263 + 31476413 = 31476676
293 + 31476383 = 31476676

Showing the first eight; more decompositions exist.
