Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592386, here are decompositions:

17 + 31592369 = 31592386
29 + 31592357 = 31592386
167 + 31592219 = 31592386
173 + 31592213 = 31592386
227 + 31592159 = 31592386
257 + 31592129 = 31592386
263 + 31592123 = 31592386
347 + 31592039 = 31592386

Showing the first eight; more decompositions exist.
