Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593128, here are decompositions:

19 + 31593109 = 31593128
31 + 31593097 = 31593128
97 + 31593031 = 31593128
157 + 31592971 = 31593128
181 + 31592947 = 31593128
331 + 31592797 = 31593128
349 + 31592779 = 31593128
367 + 31592761 = 31593128

Showing the first eight; more decompositions exist.
