Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669212, here are decompositions:

5 + 8669207 = 8669212
23 + 8669189 = 8669212
53 + 8669159 = 8669212
89 + 8669123 = 8669212
239 + 8668973 = 8669212
311 + 8668901 = 8669212
449 + 8668763 = 8669212
491 + 8668721 = 8669212

Showing the first eight; more decompositions exist.
