Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608578, here are decompositions:

5 + 8608573 = 8608578
7 + 8608571 = 8608578
29 + 8608549 = 8608578
71 + 8608507 = 8608578
89 + 8608489 = 8608578
127 + 8608451 = 8608578
149 + 8608429 = 8608578
151 + 8608427 = 8608578

Showing the first eight; more decompositions exist.
