Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593126, here are decompositions:

17 + 31593109 = 31593126
29 + 31593097 = 31593126
79 + 31593047 = 31593126
167 + 31592959 = 31593126
179 + 31592947 = 31593126
277 + 31592849 = 31593126
283 + 31592843 = 31593126
293 + 31592833 = 31593126

Showing the first eight; more decompositions exist.
