Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593474, here are decompositions:

13 + 31593461 = 31593474
37 + 31593437 = 31593474
83 + 31593391 = 31593474
97 + 31593377 = 31593474
131 + 31593343 = 31593474
167 + 31593307 = 31593474
223 + 31593251 = 31593474
277 + 31593197 = 31593474

Showing the first eight; more decompositions exist.
