Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626198, here are decompositions:

17 + 8626181 = 8626198
29 + 8626169 = 8626198
59 + 8626139 = 8626198
89 + 8626109 = 8626198
131 + 8626067 = 8626198
137 + 8626061 = 8626198
197 + 8626001 = 8626198
239 + 8625959 = 8626198

Showing the first eight; more decompositions exist.
