Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669256, here are decompositions:

5 + 8669251 = 8669256
7 + 8669249 = 8669256
17 + 8669239 = 8669256
19 + 8669237 = 8669256
23 + 8669233 = 8669256
67 + 8669189 = 8669256
97 + 8669159 = 8669256
139 + 8669117 = 8669256

Showing the first eight; more decompositions exist.
