Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583016, here are decompositions:

67 + 31582949 = 31583016
79 + 31582937 = 31583016
103 + 31582913 = 31583016
109 + 31582907 = 31583016
193 + 31582823 = 31583016
197 + 31582819 = 31583016
239 + 31582777 = 31583016
277 + 31582739 = 31583016

Showing the first eight; more decompositions exist.
