Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584338, here are decompositions:

31 + 31584307 = 31584338
127 + 31584211 = 31584338
199 + 31584139 = 31584338
271 + 31584067 = 31584338
349 + 31583989 = 31584338
367 + 31583971 = 31584338
397 + 31583941 = 31584338
811 + 31583527 = 31584338

Showing the first eight; more decompositions exist.
