Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624212, here are decompositions:

11 + 8624201 = 8624212
29 + 8624183 = 8624212
53 + 8624159 = 8624212
59 + 8624153 = 8624212
71 + 8624141 = 8624212
83 + 8624129 = 8624212
101 + 8624111 = 8624212
251 + 8623961 = 8624212

Showing the first eight; more decompositions exist.
