Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582134, here are decompositions:

13 + 31582121 = 31582134
37 + 31582097 = 31582134
41 + 31582093 = 31582134
97 + 31582037 = 31582134
107 + 31582027 = 31582134
113 + 31582021 = 31582134
131 + 31582003 = 31582134
137 + 31581997 = 31582134

Showing the first eight; more decompositions exist.
