Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593698, here are decompositions:

67 + 31593631 = 31593698
109 + 31593589 = 31593698
127 + 31593571 = 31593698
181 + 31593517 = 31593698
307 + 31593391 = 31593698
601 + 31593097 = 31593698
727 + 31592971 = 31593698
739 + 31592959 = 31593698

Showing the first eight; more decompositions exist.
