Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639108, here are decompositions:

19 + 8639089 = 8639108
97 + 8639011 = 8639108
109 + 8638999 = 8639108
157 + 8638951 = 8639108
199 + 8638909 = 8639108
241 + 8638867 = 8639108
421 + 8638687 = 8639108
487 + 8638621 = 8639108

Showing the first eight; more decompositions exist.
