Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728706, here are decompositions:

43 + 8728663 = 8728706
79 + 8728627 = 8728706
97 + 8728609 = 8728706
109 + 8728597 = 8728706
127 + 8728579 = 8728706
157 + 8728549 = 8728706
193 + 8728513 = 8728706
223 + 8728483 = 8728706

Showing the first eight; more decompositions exist.
