Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592164, here are decompositions:

3 + 31592161 = 31592164
5 + 31592159 = 31592164
41 + 31592123 = 31592164
113 + 31592051 = 31592164
167 + 31591997 = 31592164
251 + 31591913 = 31592164
431 + 31591733 = 31592164
563 + 31591601 = 31592164

Showing the first eight; more decompositions exist.
