Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649122, here are decompositions:

19 + 8649103 = 8649122
43 + 8649079 = 8649122
61 + 8649061 = 8649122
73 + 8649049 = 8649122
193 + 8648929 = 8649122
199 + 8648923 = 8649122
241 + 8648881 = 8649122
283 + 8648839 = 8649122

Showing the first eight; more decompositions exist.
