Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669530, here are decompositions:

3 + 8669527 = 8669530
17 + 8669513 = 8669530
29 + 8669501 = 8669530
41 + 8669489 = 8669530
47 + 8669483 = 8669530
53 + 8669477 = 8669530
83 + 8669447 = 8669530
113 + 8669417 = 8669530

Showing the first eight; more decompositions exist.
