Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592608, here are decompositions:

41 + 31592567 = 31592608
191 + 31592417 = 31592608
197 + 31592411 = 31592608
239 + 31592369 = 31592608
251 + 31592357 = 31592608
317 + 31592291 = 31592608
389 + 31592219 = 31592608
449 + 31592159 = 31592608

Showing the first eight; more decompositions exist.
