Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624518, here are decompositions:

11 + 8624507 = 8624518
41 + 8624477 = 8624518
59 + 8624459 = 8624518
191 + 8624327 = 8624518
251 + 8624267 = 8624518
269 + 8624249 = 8624518
281 + 8624237 = 8624518
317 + 8624201 = 8624518

Showing the first eight; more decompositions exist.
