Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669672, here are decompositions:

3 + 8669669 = 8669672
43 + 8669629 = 8669672
61 + 8669611 = 8669672
79 + 8669593 = 8669672
229 + 8669443 = 8669672
283 + 8669389 = 8669672
331 + 8669341 = 8669672
379 + 8669293 = 8669672

Showing the first eight; more decompositions exist.
