Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639154, here are decompositions:

5 + 8639149 = 8639154
11 + 8639143 = 8639154
23 + 8639131 = 8639154
31 + 8639123 = 8639154
47 + 8639107 = 8639154
103 + 8639051 = 8639154
127 + 8639027 = 8639154
157 + 8638997 = 8639154

Showing the first eight; more decompositions exist.
