Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669520, here are decompositions:

7 + 8669513 = 8669520
19 + 8669501 = 8669520
31 + 8669489 = 8669520
37 + 8669483 = 8669520
43 + 8669477 = 8669520
73 + 8669447 = 8669520
103 + 8669417 = 8669520
109 + 8669411 = 8669520

Showing the first eight; more decompositions exist.
