Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648216, here are decompositions:

37 + 8648179 = 8648216
67 + 8648149 = 8648216
103 + 8648113 = 8648216
223 + 8647993 = 8648216
337 + 8647879 = 8648216
397 + 8647819 = 8648216
433 + 8647783 = 8648216
457 + 8647759 = 8648216

Showing the first eight; more decompositions exist.
