Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582456, here are decompositions:

47 + 31582409 = 31582456
53 + 31582403 = 31582456
137 + 31582319 = 31582456
239 + 31582217 = 31582456
263 + 31582193 = 31582456
293 + 31582163 = 31582456
359 + 31582097 = 31582456
419 + 31582037 = 31582456

Showing the first eight; more decompositions exist.
