Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669810, here are decompositions:

43 + 8669767 = 8669810
109 + 8669701 = 8669810
139 + 8669671 = 8669810
181 + 8669629 = 8669810
199 + 8669611 = 8669810
283 + 8669527 = 8669810
367 + 8669443 = 8669810
421 + 8669389 = 8669810

Showing the first eight; more decompositions exist.
