Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622506, here are decompositions:

7 + 8622499 = 8622506
19 + 8622487 = 8622506
37 + 8622469 = 8622506
43 + 8622463 = 8622506
127 + 8622379 = 8622506
163 + 8622343 = 8622506
199 + 8622307 = 8622506
283 + 8622223 = 8622506

Showing the first eight; more decompositions exist.
