Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728556, here are decompositions:

7 + 8728549 = 8728556
43 + 8728513 = 8728556
73 + 8728483 = 8728556
283 + 8728273 = 8728556
349 + 8728207 = 8728556
409 + 8728147 = 8728556
619 + 8727937 = 8728556
643 + 8727913 = 8728556

Showing the first eight; more decompositions exist.
