Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669736, here are decompositions:

67 + 8669669 = 8669736
79 + 8669657 = 8669736
107 + 8669629 = 8669736
109 + 8669627 = 8669736
113 + 8669623 = 8669736
193 + 8669543 = 8669736
223 + 8669513 = 8669736
293 + 8669443 = 8669736

Showing the first eight; more decompositions exist.
