Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626180, here are decompositions:

11 + 8626169 = 8626180
41 + 8626139 = 8626180
71 + 8626109 = 8626180
113 + 8626067 = 8626180
137 + 8626043 = 8626180
179 + 8626001 = 8626180
197 + 8625983 = 8626180
347 + 8625833 = 8626180

Showing the first eight; more decompositions exist.
