Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546922, here are decompositions:

13 + 31546909 = 31546922
31 + 31546891 = 31546922
61 + 31546861 = 31546922
79 + 31546843 = 31546922
109 + 31546813 = 31546922
163 + 31546759 = 31546922
181 + 31546741 = 31546922
331 + 31546591 = 31546922

Showing the first eight; more decompositions exist.
