Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669470, here are decompositions:

23 + 8669447 = 8669470
53 + 8669417 = 8669470
59 + 8669411 = 8669470
71 + 8669399 = 8669470
137 + 8669333 = 8669470
191 + 8669279 = 8669470
233 + 8669237 = 8669470
263 + 8669207 = 8669470

Showing the first eight; more decompositions exist.
