Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639102, here are decompositions:

13 + 8639089 = 8639102
103 + 8638999 = 8639102
151 + 8638951 = 8639102
193 + 8638909 = 8639102
211 + 8638891 = 8639102
631 + 8638471 = 8639102
691 + 8638411 = 8639102
811 + 8638291 = 8639102

Showing the first eight; more decompositions exist.
