Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622578, here are decompositions:

67 + 8622511 = 8622578
79 + 8622499 = 8622578
109 + 8622469 = 8622578
157 + 8622421 = 8622578
199 + 8622379 = 8622578
241 + 8622337 = 8622578
271 + 8622307 = 8622578
277 + 8622301 = 8622578

Showing the first eight; more decompositions exist.
