Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622428, here are decompositions:

7 + 8622421 = 8622428
37 + 8622391 = 8622428
97 + 8622331 = 8622428
127 + 8622301 = 8622428
421 + 8622007 = 8622428
439 + 8621989 = 8622428
457 + 8621971 = 8622428
571 + 8621857 = 8622428

Showing the first eight; more decompositions exist.
