Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669518, here are decompositions:

5 + 8669513 = 8669518
17 + 8669501 = 8669518
29 + 8669489 = 8669518
41 + 8669477 = 8669518
71 + 8669447 = 8669518
101 + 8669417 = 8669518
107 + 8669411 = 8669518
167 + 8669351 = 8669518

Showing the first eight; more decompositions exist.
