Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476490, here are decompositions:

29 + 31476461 = 31476490
41 + 31476449 = 31476490
53 + 31476437 = 31476490
107 + 31476383 = 31476490
137 + 31476353 = 31476490
173 + 31476317 = 31476490
239 + 31476251 = 31476490
251 + 31476239 = 31476490

Showing the first eight; more decompositions exist.
