Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592824, here are decompositions:

173 + 31592651 = 31592824
257 + 31592567 = 31592824
293 + 31592531 = 31592824
401 + 31592423 = 31592824
467 + 31592357 = 31592824
701 + 31592123 = 31592824
773 + 31592051 = 31592824
827 + 31591997 = 31592824

Showing the first eight; more decompositions exist.
