Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609028, here are decompositions:

5 + 8609023 = 8609028
97 + 8608931 = 8609028
137 + 8608891 = 8609028
139 + 8608889 = 8609028
149 + 8608879 = 8609028
157 + 8608871 = 8609028
167 + 8608861 = 8609028
191 + 8608837 = 8609028

Showing the first eight; more decompositions exist.
