Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728908, here are decompositions:

5 + 8728903 = 8728908
7 + 8728901 = 8728908
11 + 8728897 = 8728908
59 + 8728849 = 8728908
101 + 8728807 = 8728908
151 + 8728757 = 8728908
191 + 8728717 = 8728908
197 + 8728711 = 8728908

Showing the first eight; more decompositions exist.
