Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609428, here are decompositions:

17 + 8609411 = 8609428
131 + 8609297 = 8609428
521 + 8608907 = 8609428
557 + 8608871 = 8609428
587 + 8608841 = 8609428
599 + 8608829 = 8609428
677 + 8608751 = 8609428
701 + 8608727 = 8609428

Showing the first eight; more decompositions exist.
