Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592832, here are decompositions:

23 + 31592809 = 31592832
53 + 31592779 = 31592832
59 + 31592773 = 31592832
71 + 31592761 = 31592832
149 + 31592683 = 31592832
181 + 31592651 = 31592832
191 + 31592641 = 31592832
211 + 31592621 = 31592832

Showing the first eight; more decompositions exist.
