Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592838, here are decompositions:

5 + 31592833 = 31592838
29 + 31592809 = 31592838
41 + 31592797 = 31592838
59 + 31592779 = 31592838
197 + 31592641 = 31592838
239 + 31592599 = 31592838
271 + 31592567 = 31592838
281 + 31592557 = 31592838

Showing the first eight; more decompositions exist.
