Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547490, here are decompositions:

11 + 31547479 = 31547490
19 + 31547471 = 31547490
31 + 31547459 = 31547490
41 + 31547449 = 31547490
151 + 31547339 = 31547490
173 + 31547317 = 31547490
193 + 31547297 = 31547490
223 + 31547267 = 31547490

Showing the first eight; more decompositions exist.
