Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453722, here are decompositions:

11 + 31453711 = 31453722
23 + 31453699 = 31453722
43 + 31453679 = 31453722
71 + 31453651 = 31453722
151 + 31453571 = 31453722
193 + 31453529 = 31453722
199 + 31453523 = 31453722
239 + 31453483 = 31453722

Showing the first eight; more decompositions exist.
