Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669616, here are decompositions:

5 + 8669611 = 8669616
23 + 8669593 = 8669616
73 + 8669543 = 8669616
89 + 8669527 = 8669616
103 + 8669513 = 8669616
127 + 8669489 = 8669616
139 + 8669477 = 8669616
173 + 8669443 = 8669616

Showing the first eight; more decompositions exist.
