Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609020, here are decompositions:

47 + 8608973 = 8609020
89 + 8608931 = 8609020
107 + 8608913 = 8609020
113 + 8608907 = 8609020
131 + 8608889 = 8609020
149 + 8608871 = 8609020
179 + 8608841 = 8609020
191 + 8608829 = 8609020

Showing the first eight; more decompositions exist.
