Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622440, here are decompositions:

19 + 8622421 = 8622440
61 + 8622379 = 8622440
67 + 8622373 = 8622440
97 + 8622343 = 8622440
103 + 8622337 = 8622440
109 + 8622331 = 8622440
139 + 8622301 = 8622440
199 + 8622241 = 8622440

Showing the first eight; more decompositions exist.
