Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649020, here are decompositions:

19 + 8649001 = 8649020
67 + 8648953 = 8649020
97 + 8648923 = 8649020
139 + 8648881 = 8649020
157 + 8648863 = 8649020
181 + 8648839 = 8649020
223 + 8648797 = 8649020
229 + 8648791 = 8649020

Showing the first eight; more decompositions exist.
