Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669628, here are decompositions:

5 + 8669623 = 8669628
7 + 8669621 = 8669628
17 + 8669611 = 8669628
101 + 8669527 = 8669628
127 + 8669501 = 8669628
139 + 8669489 = 8669628
151 + 8669477 = 8669628
181 + 8669447 = 8669628

Showing the first eight; more decompositions exist.
