Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467574, here are decompositions:

3 + 31467571 = 31467574
23 + 31467551 = 31467574
41 + 31467533 = 31467574
71 + 31467503 = 31467574
107 + 31467467 = 31467574
137 + 31467437 = 31467574
227 + 31467347 = 31467574
263 + 31467311 = 31467574

Showing the first eight; more decompositions exist.
