Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582326, here are decompositions:

5 + 31582321 = 31582326
7 + 31582319 = 31582326
59 + 31582267 = 31582326
109 + 31582217 = 31582326
163 + 31582163 = 31582326
229 + 31582097 = 31582326
233 + 31582093 = 31582326
277 + 31582049 = 31582326

Showing the first eight; more decompositions exist.
