Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678028, here are decompositions:

17 + 8678011 = 8678028
61 + 8677967 = 8678028
67 + 8677961 = 8678028
137 + 8677891 = 8678028
181 + 8677847 = 8678028
199 + 8677829 = 8678028
257 + 8677771 = 8678028
269 + 8677759 = 8678028

Showing the first eight; more decompositions exist.
