Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592638, here are decompositions:

17 + 31592621 = 31592638
71 + 31592567 = 31592638
107 + 31592531 = 31592638
149 + 31592489 = 31592638
191 + 31592447 = 31592638
227 + 31592411 = 31592638
269 + 31592369 = 31592638
281 + 31592357 = 31592638

Showing the first eight; more decompositions exist.
