Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639104, here are decompositions:

41 + 8639063 = 8639104
53 + 8639051 = 8639104
107 + 8638997 = 8639104
113 + 8638991 = 8639104
137 + 8638967 = 8639104
167 + 8638937 = 8639104
251 + 8638853 = 8639104
443 + 8638661 = 8639104

Showing the first eight; more decompositions exist.
