Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637198, here are decompositions:

19 + 8637179 = 8637198
47 + 8637151 = 8637198
67 + 8637131 = 8637198
79 + 8637119 = 8637198
107 + 8637091 = 8637198
131 + 8637067 = 8637198
137 + 8637061 = 8637198
139 + 8637059 = 8637198

Showing the first eight; more decompositions exist.
