Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649018, here are decompositions:

17 + 8649001 = 8649018
89 + 8648929 = 8649018
97 + 8648921 = 8649018
137 + 8648881 = 8649018
139 + 8648879 = 8649018
151 + 8648867 = 8649018
179 + 8648839 = 8649018
181 + 8648837 = 8649018

Showing the first eight; more decompositions exist.
