Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728994, here are decompositions:

7 + 8728987 = 8728994
31 + 8728963 = 8728994
67 + 8728927 = 8728994
73 + 8728921 = 8728994
97 + 8728897 = 8728994
277 + 8728717 = 8728994
283 + 8728711 = 8728994
331 + 8728663 = 8728994

Showing the first eight; more decompositions exist.
