Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582110, here are decompositions:

13 + 31582097 = 31582110
17 + 31582093 = 31582110
61 + 31582049 = 31582110
67 + 31582043 = 31582110
73 + 31582037 = 31582110
83 + 31582027 = 31582110
89 + 31582021 = 31582110
107 + 31582003 = 31582110

Showing the first eight; more decompositions exist.
