Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593204, here are decompositions:

7 + 31593197 = 31593204
11 + 31593193 = 31593204
31 + 31593173 = 31593204
107 + 31593097 = 31593204
157 + 31593047 = 31593204
173 + 31593031 = 31593204
193 + 31593011 = 31593204
211 + 31592993 = 31593204

Showing the first eight; more decompositions exist.
