Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658428, here are decompositions:

139 + 8658289 = 8658428
151 + 8658277 = 8658428
211 + 8658217 = 8658428
547 + 8657881 = 8658428
577 + 8657851 = 8658428
601 + 8657827 = 8658428
661 + 8657767 = 8658428
859 + 8657569 = 8658428

Showing the first eight; more decompositions exist.
