Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649158, here are decompositions:

79 + 8649079 = 8649158
97 + 8649061 = 8649158
109 + 8649049 = 8649158
157 + 8649001 = 8649158
229 + 8648929 = 8649158
277 + 8648881 = 8649158
367 + 8648791 = 8649158
379 + 8648779 = 8649158

Showing the first eight; more decompositions exist.
