Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627018, here are decompositions:

19 + 8626999 = 8627018
157 + 8626861 = 8627018
199 + 8626819 = 8627018
241 + 8626777 = 8627018
271 + 8626747 = 8627018
349 + 8626669 = 8627018
397 + 8626621 = 8627018
601 + 8626417 = 8627018

Showing the first eight; more decompositions exist.
