Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584102, here are decompositions:

59 + 31584043 = 31584102
83 + 31584019 = 31584102
103 + 31583999 = 31584102
113 + 31583989 = 31584102
131 + 31583971 = 31584102
181 + 31583921 = 31584102
191 + 31583911 = 31584102
239 + 31583863 = 31584102

Showing the first eight; more decompositions exist.
