Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584122, here are decompositions:

79 + 31584043 = 31584122
103 + 31584019 = 31584122
139 + 31583983 = 31584122
151 + 31583971 = 31584122
181 + 31583941 = 31584122
211 + 31583911 = 31584122
313 + 31583809 = 31584122
373 + 31583749 = 31584122

Showing the first eight; more decompositions exist.
