Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593922, here are decompositions:

53 + 31593869 = 31593922
83 + 31593839 = 31593922
89 + 31593833 = 31593922
233 + 31593689 = 31593922
281 + 31593641 = 31593922
293 + 31593629 = 31593922
359 + 31593563 = 31593922
389 + 31593533 = 31593922

Showing the first eight; more decompositions exist.
