Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476756, here are decompositions:

13 + 31476743 = 31476756
23 + 31476733 = 31476756
29 + 31476727 = 31476756
53 + 31476703 = 31476756
149 + 31476607 = 31476756
163 + 31476593 = 31476756
239 + 31476517 = 31476756
257 + 31476499 = 31476756

Showing the first eight; more decompositions exist.
