Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622656, here are decompositions:

79 + 8622577 = 8622656
127 + 8622529 = 8622656
157 + 8622499 = 8622656
193 + 8622463 = 8622656
277 + 8622379 = 8622656
283 + 8622373 = 8622656
313 + 8622343 = 8622656
349 + 8622307 = 8622656

Showing the first eight; more decompositions exist.
