Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582360, here are decompositions:

23 + 31582337 = 31582360
41 + 31582319 = 31582360
167 + 31582193 = 31582360
197 + 31582163 = 31582360
239 + 31582121 = 31582360
263 + 31582097 = 31582360
311 + 31582049 = 31582360
317 + 31582043 = 31582360

Showing the first eight; more decompositions exist.
