Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669984, here are decompositions:

3 + 8669981 = 8669984
61 + 8669923 = 8669984
73 + 8669911 = 8669984
163 + 8669821 = 8669984
283 + 8669701 = 8669984
313 + 8669671 = 8669984
373 + 8669611 = 8669984
457 + 8669527 = 8669984

Showing the first eight; more decompositions exist.
