Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584098, here are decompositions:

31 + 31584067 = 31584098
79 + 31584019 = 31584098
109 + 31583989 = 31584098
127 + 31583971 = 31584098
157 + 31583941 = 31584098
241 + 31583857 = 31584098
349 + 31583749 = 31584098
397 + 31583701 = 31584098

Showing the first eight; more decompositions exist.
