Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584082, here are decompositions:

83 + 31583999 = 31584082
251 + 31583831 = 31584082
263 + 31583819 = 31584082
311 + 31583771 = 31584082
353 + 31583729 = 31584082
389 + 31583693 = 31584082
419 + 31583663 = 31584082
449 + 31583633 = 31584082

Showing the first eight; more decompositions exist.
