Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728772, here are decompositions:

61 + 8728711 = 8728772
109 + 8728663 = 8728772
163 + 8728609 = 8728772
181 + 8728591 = 8728772
193 + 8728579 = 8728772
223 + 8728549 = 8728772
463 + 8728309 = 8728772
499 + 8728273 = 8728772

Showing the first eight; more decompositions exist.
