Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593012, here are decompositions:

19 + 31592993 = 31593012
29 + 31592983 = 31593012
41 + 31592971 = 31593012
53 + 31592959 = 31593012
89 + 31592923 = 31593012
163 + 31592849 = 31593012
179 + 31592833 = 31593012
233 + 31592779 = 31593012

Showing the first eight; more decompositions exist.
