Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626622, here are decompositions:

19 + 8626603 = 8626622
73 + 8626549 = 8626622
163 + 8626459 = 8626622
373 + 8626249 = 8626622
379 + 8626243 = 8626622
463 + 8626159 = 8626622
523 + 8626099 = 8626622
643 + 8625979 = 8626622

Showing the first eight; more decompositions exist.
