Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669318, here are decompositions:

67 + 8669251 = 8669318
79 + 8669239 = 8669318
139 + 8669179 = 8669318
211 + 8669107 = 8669318
277 + 8669041 = 8669318
367 + 8668951 = 8669318
421 + 8668897 = 8669318
487 + 8668831 = 8669318

Showing the first eight; more decompositions exist.
