Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453922, here are decompositions:

13 + 31453909 = 31453922
43 + 31453879 = 31453922
109 + 31453813 = 31453922
139 + 31453783 = 31453922
211 + 31453711 = 31453922
223 + 31453699 = 31453922
271 + 31453651 = 31453922
421 + 31453501 = 31453922

Showing the first eight; more decompositions exist.
