Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649108, here are decompositions:

5 + 8649103 = 8649108
29 + 8649079 = 8649108
37 + 8649071 = 8649108
47 + 8649061 = 8649108
59 + 8649049 = 8649108
79 + 8649029 = 8649108
107 + 8649001 = 8649108
179 + 8648929 = 8649108

Showing the first eight; more decompositions exist.
