Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582222, here are decompositions:

5 + 31582217 = 31582222
29 + 31582193 = 31582222
59 + 31582163 = 31582222
101 + 31582121 = 31582222
173 + 31582049 = 31582222
179 + 31582043 = 31582222
239 + 31581983 = 31582222
311 + 31581911 = 31582222

Showing the first eight; more decompositions exist.
