Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593288, here are decompositions:

37 + 31593251 = 31593288
179 + 31593109 = 31593288
191 + 31593097 = 31593288
241 + 31593047 = 31593288
257 + 31593031 = 31593288
277 + 31593011 = 31593288
317 + 31592971 = 31593288
367 + 31592921 = 31593288

Showing the first eight; more decompositions exist.
