Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624250, here are decompositions:

7 + 8624243 = 8624250
13 + 8624237 = 8624250
29 + 8624221 = 8624250
59 + 8624191 = 8624250
67 + 8624183 = 8624250
71 + 8624179 = 8624250
73 + 8624177 = 8624250
97 + 8624153 = 8624250

Showing the first eight; more decompositions exist.
