Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584108, here are decompositions:

7 + 31584101 = 31584108
41 + 31584067 = 31584108
89 + 31584019 = 31584108
109 + 31583999 = 31584108
137 + 31583971 = 31584108
167 + 31583941 = 31584108
197 + 31583911 = 31584108
211 + 31583897 = 31584108

Showing the first eight; more decompositions exist.
