Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648198, here are decompositions:

7 + 8648191 = 8648198
19 + 8648179 = 8648198
67 + 8648131 = 8648198
271 + 8647927 = 8648198
379 + 8647819 = 8648198
397 + 8647801 = 8648198
439 + 8647759 = 8648198
487 + 8647711 = 8648198

Showing the first eight; more decompositions exist.
