Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592828, here are decompositions:

19 + 31592809 = 31592828
31 + 31592797 = 31592828
67 + 31592761 = 31592828
151 + 31592677 = 31592828
229 + 31592599 = 31592828
271 + 31592557 = 31592828
277 + 31592551 = 31592828
439 + 31592389 = 31592828

Showing the first eight; more decompositions exist.
