Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592274, here are decompositions:

17 + 31592257 = 31592274
61 + 31592213 = 31592274
71 + 31592203 = 31592274
101 + 31592173 = 31592274
113 + 31592161 = 31592274
151 + 31592123 = 31592274
223 + 31592051 = 31592274
227 + 31592047 = 31592274

Showing the first eight; more decompositions exist.
