Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624258, here are decompositions:

7 + 8624251 = 8624258
37 + 8624221 = 8624258
67 + 8624191 = 8624258
79 + 8624179 = 8624258
127 + 8624131 = 8624258
157 + 8624101 = 8624258
199 + 8624059 = 8624258
241 + 8624017 = 8624258

Showing the first eight; more decompositions exist.
