Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665018, here are decompositions:

41 + 8664977 = 8665018
59 + 8664959 = 8665018
71 + 8664947 = 8665018
149 + 8664869 = 8665018
227 + 8664791 = 8665018
317 + 8664701 = 8665018
347 + 8664671 = 8665018
491 + 8664527 = 8665018

Showing the first eight; more decompositions exist.
