Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624210, here are decompositions:

19 + 8624191 = 8624210
31 + 8624179 = 8624210
73 + 8624137 = 8624210
79 + 8624131 = 8624210
109 + 8624101 = 8624210
151 + 8624059 = 8624210
193 + 8624017 = 8624210
241 + 8623969 = 8624210

Showing the first eight; more decompositions exist.
