Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582176, here are decompositions:

5 + 31582171 = 31582176
13 + 31582163 = 31582176
79 + 31582097 = 31582176
83 + 31582093 = 31582176
127 + 31582049 = 31582176
139 + 31582037 = 31582176
149 + 31582027 = 31582176
173 + 31582003 = 31582176

Showing the first eight; more decompositions exist.
