Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592732, here are decompositions:

181 + 31592551 = 31592732
421 + 31592311 = 31592732
571 + 31592161 = 31592732
733 + 31591999 = 31592732
739 + 31591993 = 31592732
823 + 31591909 = 31592732
859 + 31591873 = 31592732
1009 + 31591723 = 31592732

Showing the first eight; more decompositions exist.
