Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659028, here are decompositions:

19 + 8659009 = 8659028
31 + 8658997 = 8659028
67 + 8658961 = 8659028
97 + 8658931 = 8659028
109 + 8658919 = 8659028
151 + 8658877 = 8659028
181 + 8658847 = 8659028
199 + 8658829 = 8659028

Showing the first eight; more decompositions exist.
