Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593396, here are decompositions:

5 + 31593391 = 31593396
7 + 31593389 = 31593396
19 + 31593377 = 31593396
53 + 31593343 = 31593396
83 + 31593313 = 31593396
89 + 31593307 = 31593396
97 + 31593299 = 31593396
199 + 31593197 = 31593396

Showing the first eight; more decompositions exist.
