Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626386, here are decompositions:

37 + 8626349 = 8626386
89 + 8626297 = 8626386
103 + 8626283 = 8626386
137 + 8626249 = 8626386
149 + 8626237 = 8626386
157 + 8626229 = 8626386
227 + 8626159 = 8626386
257 + 8626129 = 8626386

Showing the first eight; more decompositions exist.
