Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593264, here are decompositions:

11 + 31593253 = 31593264
13 + 31593251 = 31593264
67 + 31593197 = 31593264
71 + 31593193 = 31593264
167 + 31593097 = 31593264
233 + 31593031 = 31593264
271 + 31592993 = 31593264
281 + 31592983 = 31593264

Showing the first eight; more decompositions exist.
