Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728550, here are decompositions:

37 + 8728513 = 8728550
67 + 8728483 = 8728550
79 + 8728471 = 8728550
163 + 8728387 = 8728550
241 + 8728309 = 8728550
277 + 8728273 = 8728550
421 + 8728129 = 8728550
613 + 8727937 = 8728550

Showing the first eight; more decompositions exist.
