Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622566, here are decompositions:

3 + 8622563 = 8622566
37 + 8622529 = 8622566
67 + 8622499 = 8622566
79 + 8622487 = 8622566
97 + 8622469 = 8622566
103 + 8622463 = 8622566
193 + 8622373 = 8622566
223 + 8622343 = 8622566

Showing the first eight; more decompositions exist.
