Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593466, here are decompositions:

5 + 31593461 = 31593466
29 + 31593437 = 31593466
89 + 31593377 = 31593466
167 + 31593299 = 31593466
269 + 31593197 = 31593466
293 + 31593173 = 31593466
419 + 31593047 = 31593466
617 + 31592849 = 31593466

Showing the first eight; more decompositions exist.
