Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624420, here are decompositions:

37 + 8624383 = 8624420
67 + 8624353 = 8624420
97 + 8624323 = 8624420
109 + 8624311 = 8624420
199 + 8624221 = 8624420
229 + 8624191 = 8624420
241 + 8624179 = 8624420
283 + 8624137 = 8624420

Showing the first eight; more decompositions exist.
