Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592896, here are decompositions:

47 + 31592849 = 31592896
53 + 31592843 = 31592896
149 + 31592747 = 31592896
233 + 31592663 = 31592896
443 + 31592453 = 31592896
449 + 31592447 = 31592896
479 + 31592417 = 31592896
677 + 31592219 = 31592896

Showing the first eight; more decompositions exist.
