Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584092, here are decompositions:

73 + 31584019 = 31584092
103 + 31583989 = 31584092
109 + 31583983 = 31584092
151 + 31583941 = 31584092
181 + 31583911 = 31584092
229 + 31583863 = 31584092
283 + 31583809 = 31584092
313 + 31583779 = 31584092

Showing the first eight; more decompositions exist.
