Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624686, here are decompositions:

17 + 8624669 = 8624686
53 + 8624633 = 8624686
113 + 8624573 = 8624686
179 + 8624507 = 8624686
227 + 8624459 = 8624686
293 + 8624393 = 8624686
359 + 8624327 = 8624686
419 + 8624267 = 8624686

Showing the first eight; more decompositions exist.
