Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584848, here are decompositions:

19 + 31584829 = 31584848
79 + 31584769 = 31584848
151 + 31584697 = 31584848
181 + 31584667 = 31584848
241 + 31584607 = 31584848
271 + 31584577 = 31584848
307 + 31584541 = 31584848
349 + 31584499 = 31584848

Showing the first eight; more decompositions exist.
