Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669280, here are decompositions:

29 + 8669251 = 8669280
31 + 8669249 = 8669280
41 + 8669239 = 8669280
43 + 8669237 = 8669280
47 + 8669233 = 8669280
73 + 8669207 = 8669280
101 + 8669179 = 8669280
157 + 8669123 = 8669280

Showing the first eight; more decompositions exist.
