Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669690, here are decompositions:

19 + 8669671 = 8669690
61 + 8669629 = 8669690
67 + 8669623 = 8669690
79 + 8669611 = 8669690
97 + 8669593 = 8669690
163 + 8669527 = 8669690
349 + 8669341 = 8669690
373 + 8669317 = 8669690

Showing the first eight; more decompositions exist.
