Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624986, here are decompositions:

5 + 8624981 = 8624986
113 + 8624873 = 8624986
179 + 8624807 = 8624986
233 + 8624753 = 8624986
269 + 8624717 = 8624986
317 + 8624669 = 8624986
353 + 8624633 = 8624986
479 + 8624507 = 8624986

Showing the first eight; more decompositions exist.
