Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582276, here are decompositions:

59 + 31582217 = 31582276
83 + 31582193 = 31582276
113 + 31582163 = 31582276
179 + 31582097 = 31582276
227 + 31582049 = 31582276
233 + 31582043 = 31582276
239 + 31582037 = 31582276
293 + 31581983 = 31582276

Showing the first eight; more decompositions exist.
