Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668908, here are decompositions:

7 + 8668901 = 8668908
11 + 8668897 = 8668908
19 + 8668889 = 8668908
71 + 8668837 = 8668908
107 + 8668801 = 8668908
109 + 8668799 = 8668908
167 + 8668741 = 8668908
197 + 8668711 = 8668908

Showing the first eight; more decompositions exist.
