Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592656, here are decompositions:

5 + 31592651 = 31592656
89 + 31592567 = 31592656
167 + 31592489 = 31592656
233 + 31592423 = 31592656
239 + 31592417 = 31592656
443 + 31592213 = 31592656
617 + 31592039 = 31592656
659 + 31591997 = 31592656

Showing the first eight; more decompositions exist.
