Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669630, here are decompositions:

3 + 8669627 = 8669630
7 + 8669623 = 8669630
19 + 8669611 = 8669630
37 + 8669593 = 8669630
103 + 8669527 = 8669630
241 + 8669389 = 8669630
313 + 8669317 = 8669630
337 + 8669293 = 8669630

Showing the first eight; more decompositions exist.
