Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592662, here are decompositions:

11 + 31592651 = 31592662
41 + 31592621 = 31592662
131 + 31592531 = 31592662
173 + 31592489 = 31592662
239 + 31592423 = 31592662
251 + 31592411 = 31592662
293 + 31592369 = 31592662
443 + 31592219 = 31592662

Showing the first eight; more decompositions exist.
