Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609278, here are decompositions:

5 + 8609273 = 8609278
71 + 8609207 = 8609278
149 + 8609129 = 8609278
179 + 8609099 = 8609278
191 + 8609087 = 8609278
347 + 8608931 = 8609278
389 + 8608889 = 8609278
449 + 8608829 = 8609278

Showing the first eight; more decompositions exist.
