Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728764, here are decompositions:

7 + 8728757 = 8728764
43 + 8728721 = 8728764
47 + 8728717 = 8728764
53 + 8728711 = 8728764
73 + 8728691 = 8728764
101 + 8728663 = 8728764
137 + 8728627 = 8728764
157 + 8728607 = 8728764

Showing the first eight; more decompositions exist.
