Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593504, here are decompositions:

13 + 31593491 = 31593504
43 + 31593461 = 31593504
67 + 31593437 = 31593504
113 + 31593391 = 31593504
127 + 31593377 = 31593504
191 + 31593313 = 31593504
197 + 31593307 = 31593504
251 + 31593253 = 31593504

Showing the first eight; more decompositions exist.
