Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583104, here are decompositions:

17 + 31583087 = 31583104
23 + 31583081 = 31583104
53 + 31583051 = 31583104
71 + 31583033 = 31583104
167 + 31582937 = 31583104
173 + 31582931 = 31583104
191 + 31582913 = 31583104
197 + 31582907 = 31583104

Showing the first eight; more decompositions exist.
