Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669662, here are decompositions:

5 + 8669657 = 8669662
11 + 8669651 = 8669662
41 + 8669621 = 8669662
149 + 8669513 = 8669662
173 + 8669489 = 8669662
179 + 8669483 = 8669662
251 + 8669411 = 8669662
263 + 8669399 = 8669662

Showing the first eight; more decompositions exist.
