Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592958, here are decompositions:

11 + 31592947 = 31592958
37 + 31592921 = 31592958
109 + 31592849 = 31592958
149 + 31592809 = 31592958
179 + 31592779 = 31592958
197 + 31592761 = 31592958
211 + 31592747 = 31592958
281 + 31592677 = 31592958

Showing the first eight; more decompositions exist.
