Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582104, here are decompositions:

7 + 31582097 = 31582104
11 + 31582093 = 31582104
61 + 31582043 = 31582104
67 + 31582037 = 31582104
83 + 31582021 = 31582104
101 + 31582003 = 31582104
107 + 31581997 = 31582104
131 + 31581973 = 31582104

Showing the first eight; more decompositions exist.
