Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475482, here are decompositions:

11 + 31475471 = 31475482
23 + 31475459 = 31475482
29 + 31475453 = 31475482
53 + 31475429 = 31475482
89 + 31475393 = 31475482
239 + 31475243 = 31475482
251 + 31475231 = 31475482
293 + 31475189 = 31475482

Showing the first eight; more decompositions exist.
