Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625028, here are decompositions:

17 + 8625011 = 8625028
29 + 8624999 = 8625028
47 + 8624981 = 8625028
107 + 8624921 = 8625028
257 + 8624771 = 8625028
311 + 8624717 = 8625028
359 + 8624669 = 8625028
521 + 8624507 = 8625028

Showing the first eight; more decompositions exist.
