Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584124, here are decompositions:

23 + 31584101 = 31584124
227 + 31583897 = 31584124
293 + 31583831 = 31584124
347 + 31583777 = 31584124
353 + 31583771 = 31584124
431 + 31583693 = 31584124
461 + 31583663 = 31584124
491 + 31583633 = 31584124

Showing the first eight; more decompositions exist.
