Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669488, here are decompositions:

5 + 8669483 = 8669488
11 + 8669477 = 8669488
41 + 8669447 = 8669488
71 + 8669417 = 8669488
89 + 8669399 = 8669488
137 + 8669351 = 8669488
239 + 8669249 = 8669488
251 + 8669237 = 8669488

Showing the first eight; more decompositions exist.
