Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605020, here are decompositions:

19 + 8605001 = 8605020
29 + 8604991 = 8605020
37 + 8604983 = 8605020
43 + 8604977 = 8605020
59 + 8604961 = 8605020
107 + 8604913 = 8605020
157 + 8604863 = 8605020
197 + 8604823 = 8605020

Showing the first eight; more decompositions exist.
