Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582324, here are decompositions:

3 + 31582321 = 31582324
5 + 31582319 = 31582324
83 + 31582241 = 31582324
107 + 31582217 = 31582324
131 + 31582193 = 31582324
227 + 31582097 = 31582324
281 + 31582043 = 31582324
443 + 31581881 = 31582324

Showing the first eight; more decompositions exist.
