Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669584, here are decompositions:

41 + 8669543 = 8669584
71 + 8669513 = 8669584
83 + 8669501 = 8669584
101 + 8669483 = 8669584
107 + 8669477 = 8669584
137 + 8669447 = 8669584
167 + 8669417 = 8669584
173 + 8669411 = 8669584

Showing the first eight; more decompositions exist.
