Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626458, here are decompositions:

37 + 8626421 = 8626458
41 + 8626417 = 8626458
67 + 8626391 = 8626458
109 + 8626349 = 8626458
157 + 8626301 = 8626458
229 + 8626229 = 8626458
277 + 8626181 = 8626458
317 + 8626141 = 8626458

Showing the first eight; more decompositions exist.
