Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453892, here are decompositions:

13 + 31453879 = 31453892
79 + 31453813 = 31453892
109 + 31453783 = 31453892
181 + 31453711 = 31453892
193 + 31453699 = 31453892
241 + 31453651 = 31453892
409 + 31453483 = 31453892
499 + 31453393 = 31453892

Showing the first eight; more decompositions exist.
