Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582354, here are decompositions:

17 + 31582337 = 31582354
113 + 31582241 = 31582354
137 + 31582217 = 31582354
191 + 31582163 = 31582354
233 + 31582121 = 31582354
257 + 31582097 = 31582354
311 + 31582043 = 31582354
317 + 31582037 = 31582354

Showing the first eight; more decompositions exist.
