Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593688, here are decompositions:

41 + 31593647 = 31593688
47 + 31593641 = 31593688
59 + 31593629 = 31593688
197 + 31593491 = 31593688
227 + 31593461 = 31593688
251 + 31593437 = 31593688
311 + 31593377 = 31593688
389 + 31593299 = 31593688

Showing the first eight; more decompositions exist.
