Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609378, here are decompositions:

7 + 8609371 = 8609378
31 + 8609347 = 8609378
97 + 8609281 = 8609378
109 + 8609269 = 8609378
139 + 8609239 = 8609378
229 + 8609149 = 8609378
241 + 8609137 = 8609378
487 + 8608891 = 8609378

Showing the first eight; more decompositions exist.
