Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592808, here are decompositions:

11 + 31592797 = 31592808
29 + 31592779 = 31592808
47 + 31592761 = 31592808
61 + 31592747 = 31592808
131 + 31592677 = 31592808
157 + 31592651 = 31592808
167 + 31592641 = 31592808
241 + 31592567 = 31592808

Showing the first eight; more decompositions exist.
