Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669636, here are decompositions:

7 + 8669629 = 8669636
13 + 8669623 = 8669636
43 + 8669593 = 8669636
109 + 8669527 = 8669636
193 + 8669443 = 8669636
307 + 8669329 = 8669636
397 + 8669239 = 8669636
457 + 8669179 = 8669636

Showing the first eight; more decompositions exist.
