Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649066, here are decompositions:

5 + 8649061 = 8649066
17 + 8649049 = 8649066
37 + 8649029 = 8649066
43 + 8649023 = 8649066
113 + 8648953 = 8649066
137 + 8648929 = 8649066
199 + 8648867 = 8649066
227 + 8648839 = 8649066

Showing the first eight; more decompositions exist.
