Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669528, here are decompositions:

139 + 8669389 = 8669528
199 + 8669329 = 8669528
211 + 8669317 = 8669528
277 + 8669251 = 8669528
349 + 8669179 = 8669528
421 + 8669107 = 8669528
457 + 8669071 = 8669528
487 + 8669041 = 8669528

Showing the first eight; more decompositions exist.
