Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582234, here are decompositions:

17 + 31582217 = 31582234
41 + 31582193 = 31582234
71 + 31582163 = 31582234
113 + 31582121 = 31582234
137 + 31582097 = 31582234
191 + 31582043 = 31582234
197 + 31582037 = 31582234
251 + 31581983 = 31582234

Showing the first eight; more decompositions exist.
