Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669770, here are decompositions:

3 + 8669767 = 8669770
101 + 8669669 = 8669770
113 + 8669657 = 8669770
149 + 8669621 = 8669770
227 + 8669543 = 8669770
257 + 8669513 = 8669770
269 + 8669501 = 8669770
281 + 8669489 = 8669770

Showing the first eight; more decompositions exist.
