Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592226, here are decompositions:

7 + 31592219 = 31592226
13 + 31592213 = 31592226
23 + 31592203 = 31592226
53 + 31592173 = 31592226
67 + 31592159 = 31592226
97 + 31592129 = 31592226
103 + 31592123 = 31592226
173 + 31592053 = 31592226

Showing the first eight; more decompositions exist.
