Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669772, here are decompositions:

5 + 8669767 = 8669772
71 + 8669701 = 8669772
101 + 8669671 = 8669772
103 + 8669669 = 8669772
149 + 8669623 = 8669772
151 + 8669621 = 8669772
179 + 8669593 = 8669772
229 + 8669543 = 8669772

Showing the first eight; more decompositions exist.
