Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583176, here are decompositions:

5 + 31583171 = 31583176
17 + 31583159 = 31583176
29 + 31583147 = 31583176
89 + 31583087 = 31583176
227 + 31582949 = 31583176
239 + 31582937 = 31583176
263 + 31582913 = 31583176
269 + 31582907 = 31583176

Showing the first eight; more decompositions exist.
