Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669780, here are decompositions:

3 + 8669777 = 8669780
13 + 8669767 = 8669780
79 + 8669701 = 8669780
109 + 8669671 = 8669780
151 + 8669629 = 8669780
157 + 8669623 = 8669780
337 + 8669443 = 8669780
439 + 8669341 = 8669780

Showing the first eight; more decompositions exist.
