Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643198, here are decompositions:

17 + 8643181 = 8643198
61 + 8643137 = 8643198
89 + 8643109 = 8643198
107 + 8643091 = 8643198
139 + 8643059 = 8643198
251 + 8642947 = 8643198
271 + 8642927 = 8643198
337 + 8642861 = 8643198

Showing the first eight; more decompositions exist.
