Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625566, here are decompositions:

7 + 8625559 = 8625566
13 + 8625553 = 8625566
73 + 8625493 = 8625566
223 + 8625343 = 8625566
277 + 8625289 = 8625566
337 + 8625229 = 8625566
379 + 8625187 = 8625566
613 + 8624953 = 8625566

Showing the first eight; more decompositions exist.
