Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583086, here are decompositions:

5 + 31583081 = 31583086
53 + 31583033 = 31583086
137 + 31582949 = 31583086
149 + 31582937 = 31583086
173 + 31582913 = 31583086
179 + 31582907 = 31583086
239 + 31582847 = 31583086
263 + 31582823 = 31583086

Showing the first eight; more decompositions exist.
