Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624446, here are decompositions:

53 + 8624393 = 8624446
179 + 8624267 = 8624446
197 + 8624249 = 8624446
263 + 8624183 = 8624446
269 + 8624177 = 8624446
293 + 8624153 = 8624446
317 + 8624129 = 8624446
419 + 8624027 = 8624446

Showing the first eight; more decompositions exist.
