Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624230, here are decompositions:

29 + 8624201 = 8624230
47 + 8624183 = 8624230
53 + 8624177 = 8624230
71 + 8624159 = 8624230
89 + 8624141 = 8624230
101 + 8624129 = 8624230
179 + 8624051 = 8624230
227 + 8624003 = 8624230

Showing the first eight; more decompositions exist.
