Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593892, here are decompositions:

23 + 31593869 = 31593892
53 + 31593839 = 31593892
59 + 31593833 = 31593892
173 + 31593719 = 31593892
251 + 31593641 = 31593892
263 + 31593629 = 31593892
359 + 31593533 = 31593892
389 + 31593503 = 31593892

Showing the first eight; more decompositions exist.
