Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669538, here are decompositions:

11 + 8669527 = 8669538
37 + 8669501 = 8669538
61 + 8669477 = 8669538
127 + 8669411 = 8669538
139 + 8669399 = 8669538
149 + 8669389 = 8669538
197 + 8669341 = 8669538
331 + 8669207 = 8669538

Showing the first eight; more decompositions exist.
