Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626158, here are decompositions:

17 + 8626141 = 8626158
19 + 8626139 = 8626158
29 + 8626129 = 8626158
59 + 8626099 = 8626158
97 + 8626061 = 8626158
157 + 8626001 = 8626158
179 + 8625979 = 8626158
197 + 8625961 = 8626158

Showing the first eight; more decompositions exist.
