Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609394, here are decompositions:

23 + 8609371 = 8609394
41 + 8609353 = 8609394
47 + 8609347 = 8609394
61 + 8609333 = 8609394
71 + 8609323 = 8609394
97 + 8609297 = 8609394
107 + 8609287 = 8609394
113 + 8609281 = 8609394

Showing the first eight; more decompositions exist.
