Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592326, here are decompositions:

107 + 31592219 = 31592326
113 + 31592213 = 31592326
167 + 31592159 = 31592326
197 + 31592129 = 31592326
347 + 31591979 = 31592326
587 + 31591739 = 31592326
593 + 31591733 = 31592326
659 + 31591667 = 31592326

Showing the first eight; more decompositions exist.
