Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593668, here are decompositions:

37 + 31593631 = 31593668
61 + 31593607 = 31593668
79 + 31593589 = 31593668
97 + 31593571 = 31593668
151 + 31593517 = 31593668
157 + 31593511 = 31593668
277 + 31593391 = 31593668
571 + 31593097 = 31593668

Showing the first eight; more decompositions exist.
