Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624450, here are decompositions:

67 + 8624383 = 8624450
97 + 8624353 = 8624450
127 + 8624323 = 8624450
139 + 8624311 = 8624450
199 + 8624251 = 8624450
229 + 8624221 = 8624450
271 + 8624179 = 8624450
313 + 8624137 = 8624450

Showing the first eight; more decompositions exist.
