Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592650, here are decompositions:

29 + 31592621 = 31592650
83 + 31592567 = 31592650
197 + 31592453 = 31592650
227 + 31592423 = 31592650
233 + 31592417 = 31592650
239 + 31592411 = 31592650
281 + 31592369 = 31592650
293 + 31592357 = 31592650

Showing the first eight; more decompositions exist.
