Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582266, here are decompositions:

17 + 31582249 = 31582266
59 + 31582207 = 31582266
73 + 31582193 = 31582266
83 + 31582183 = 31582266
103 + 31582163 = 31582266
173 + 31582093 = 31582266
223 + 31582043 = 31582266
229 + 31582037 = 31582266

Showing the first eight; more decompositions exist.
