Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593156, here are decompositions:

47 + 31593109 = 31593156
59 + 31593097 = 31593156
109 + 31593047 = 31593156
163 + 31592993 = 31593156
173 + 31592983 = 31593156
197 + 31592959 = 31593156
233 + 31592923 = 31593156
307 + 31592849 = 31593156

Showing the first eight; more decompositions exist.
