Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592290, here are decompositions:

71 + 31592219 = 31592290
131 + 31592159 = 31592290
167 + 31592123 = 31592290
239 + 31592051 = 31592290
251 + 31592039 = 31592290
293 + 31591997 = 31592290
311 + 31591979 = 31592290
557 + 31591733 = 31592290

Showing the first eight; more decompositions exist.
