Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583164, here are decompositions:

5 + 31583159 = 31583164
17 + 31583147 = 31583164
83 + 31583081 = 31583164
113 + 31583051 = 31583164
131 + 31583033 = 31583164
227 + 31582937 = 31583164
233 + 31582931 = 31583164
251 + 31582913 = 31583164

Showing the first eight; more decompositions exist.
