Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650020, here are decompositions:

17 + 8650003 = 8650020
47 + 8649973 = 8650020
53 + 8649967 = 8650020
83 + 8649937 = 8650020
109 + 8649911 = 8650020
139 + 8649881 = 8650020
149 + 8649871 = 8650020
151 + 8649869 = 8650020

Showing the first eight; more decompositions exist.
