Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584030, here are decompositions:

11 + 31584019 = 31584030
31 + 31583999 = 31584030
41 + 31583989 = 31584030
47 + 31583983 = 31584030
59 + 31583971 = 31584030
89 + 31583941 = 31584030
109 + 31583921 = 31584030
167 + 31583863 = 31584030

Showing the first eight; more decompositions exist.
