Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626618, here are decompositions:

5 + 8626613 = 8626618
41 + 8626577 = 8626618
89 + 8626529 = 8626618
101 + 8626517 = 8626618
131 + 8626487 = 8626618
149 + 8626469 = 8626618
197 + 8626421 = 8626618
227 + 8626391 = 8626618

Showing the first eight; more decompositions exist.
