Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593498, here are decompositions:

7 + 31593491 = 31593498
19 + 31593479 = 31593498
37 + 31593461 = 31593498
61 + 31593437 = 31593498
107 + 31593391 = 31593498
109 + 31593389 = 31593498
191 + 31593307 = 31593498
199 + 31593299 = 31593498

Showing the first eight; more decompositions exist.
