Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706020, here are decompositions:

7 + 8706013 = 8706020
13 + 8706007 = 8706020
19 + 8706001 = 8706020
61 + 8705959 = 8706020
79 + 8705941 = 8706020
97 + 8705923 = 8706020
109 + 8705911 = 8706020
139 + 8705881 = 8706020

Showing the first eight; more decompositions exist.
