Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636148, here are decompositions:

7 + 8636141 = 8636148
11 + 8636137 = 8636148
19 + 8636129 = 8636148
41 + 8636107 = 8636148
61 + 8636087 = 8636148
67 + 8636081 = 8636148
109 + 8636039 = 8636148
127 + 8636021 = 8636148

Showing the first eight; more decompositions exist.
