Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728904, here are decompositions:

3 + 8728901 = 8728904
7 + 8728897 = 8728904
97 + 8728807 = 8728904
193 + 8728711 = 8728904
241 + 8728663 = 8728904
277 + 8728627 = 8728904
307 + 8728597 = 8728904
313 + 8728591 = 8728904

Showing the first eight; more decompositions exist.
