Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592356, here are decompositions:

137 + 31592219 = 31592356
197 + 31592159 = 31592356
227 + 31592129 = 31592356
233 + 31592123 = 31592356
317 + 31592039 = 31592356
359 + 31591997 = 31592356
443 + 31591913 = 31592356
563 + 31591793 = 31592356

Showing the first eight; more decompositions exist.
