Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584260, here are decompositions:

13 + 31584247 = 31584260
67 + 31584193 = 31584260
193 + 31584067 = 31584260
241 + 31584019 = 31584260
271 + 31583989 = 31584260
277 + 31583983 = 31584260
349 + 31583911 = 31584260
397 + 31583863 = 31584260

Showing the first eight; more decompositions exist.
