Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592942, here are decompositions:

19 + 31592923 = 31592942
109 + 31592833 = 31592942
163 + 31592779 = 31592942
181 + 31592761 = 31592942
631 + 31592311 = 31592942
739 + 31592203 = 31592942
769 + 31592173 = 31592942
1033 + 31591909 = 31592942

Showing the first eight; more decompositions exist.
