Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669820, here are decompositions:

43 + 8669777 = 8669820
53 + 8669767 = 8669820
149 + 8669671 = 8669820
151 + 8669669 = 8669820
163 + 8669657 = 8669820
191 + 8669629 = 8669820
193 + 8669627 = 8669820
197 + 8669623 = 8669820

Showing the first eight; more decompositions exist.
