Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657020, here are decompositions:

3 + 8657017 = 8657020
11 + 8657009 = 8657020
41 + 8656979 = 8657020
101 + 8656919 = 8657020
149 + 8656871 = 8657020
173 + 8656847 = 8657020
191 + 8656829 = 8657020
233 + 8656787 = 8657020

Showing the first eight; more decompositions exist.
