Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624220, here are decompositions:

19 + 8624201 = 8624220
29 + 8624191 = 8624220
37 + 8624183 = 8624220
41 + 8624179 = 8624220
43 + 8624177 = 8624220
61 + 8624159 = 8624220
67 + 8624153 = 8624220
79 + 8624141 = 8624220

Showing the first eight; more decompositions exist.
