Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669806, here are decompositions:

29 + 8669777 = 8669806
137 + 8669669 = 8669806
149 + 8669657 = 8669806
179 + 8669627 = 8669806
263 + 8669543 = 8669806
293 + 8669513 = 8669806
317 + 8669489 = 8669806
359 + 8669447 = 8669806

Showing the first eight; more decompositions exist.
