Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582116, here are decompositions:

19 + 31582097 = 31582116
23 + 31582093 = 31582116
67 + 31582049 = 31582116
73 + 31582043 = 31582116
79 + 31582037 = 31582116
89 + 31582027 = 31582116
113 + 31582003 = 31582116
227 + 31581889 = 31582116

Showing the first eight; more decompositions exist.
