Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475492, here are decompositions:

3 + 31475489 = 31475492
151 + 31475341 = 31475492
241 + 31475251 = 31475492
283 + 31475209 = 31475492
409 + 31475083 = 31475492
421 + 31475071 = 31475492
439 + 31475053 = 31475492
463 + 31475029 = 31475492

Showing the first eight; more decompositions exist.
