Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608646, here are decompositions:

19 + 8608627 = 8608646
37 + 8608609 = 8608646
43 + 8608603 = 8608646
73 + 8608573 = 8608646
97 + 8608549 = 8608646
103 + 8608543 = 8608646
139 + 8608507 = 8608646
157 + 8608489 = 8608646

Showing the first eight; more decompositions exist.
