Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624628, here are decompositions:

7 + 8624621 = 8624628
11 + 8624617 = 8624628
29 + 8624599 = 8624628
151 + 8624477 = 8624628
179 + 8624449 = 8624628
317 + 8624311 = 8624628
379 + 8624249 = 8624628
449 + 8624179 = 8624628

Showing the first eight; more decompositions exist.
