Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669444, here are decompositions:

103 + 8669341 = 8669444
127 + 8669317 = 8669444
151 + 8669293 = 8669444
193 + 8669251 = 8669444
211 + 8669233 = 8669444
331 + 8669113 = 8669444
337 + 8669107 = 8669444
373 + 8669071 = 8669444

Showing the first eight; more decompositions exist.
