Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669650, here are decompositions:

23 + 8669627 = 8669650
29 + 8669621 = 8669650
107 + 8669543 = 8669650
137 + 8669513 = 8669650
149 + 8669501 = 8669650
167 + 8669483 = 8669650
173 + 8669477 = 8669650
233 + 8669417 = 8669650

Showing the first eight; more decompositions exist.
