Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609406, here are decompositions:

53 + 8609353 = 8609406
59 + 8609347 = 8609406
73 + 8609333 = 8609406
83 + 8609323 = 8609406
97 + 8609309 = 8609406
109 + 8609297 = 8609406
137 + 8609269 = 8609406
149 + 8609257 = 8609406

Showing the first eight; more decompositions exist.
