Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624320, here are decompositions:

53 + 8624267 = 8624320
71 + 8624249 = 8624320
83 + 8624237 = 8624320
137 + 8624183 = 8624320
167 + 8624153 = 8624320
179 + 8624141 = 8624320
191 + 8624129 = 8624320
269 + 8624051 = 8624320

Showing the first eight; more decompositions exist.
