Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582096, here are decompositions:

3 + 31582093 = 31582096
47 + 31582049 = 31582096
53 + 31582043 = 31582096
59 + 31582037 = 31582096
113 + 31581983 = 31582096
149 + 31581947 = 31582096
233 + 31581863 = 31582096
317 + 31581779 = 31582096

Showing the first eight; more decompositions exist.
