Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592826, here are decompositions:

17 + 31592809 = 31592826
29 + 31592797 = 31592826
47 + 31592779 = 31592826
53 + 31592773 = 31592826
79 + 31592747 = 31592826
149 + 31592677 = 31592826
163 + 31592663 = 31592826
227 + 31592599 = 31592826

Showing the first eight; more decompositions exist.
