Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669574, here are decompositions:

31 + 8669543 = 8669574
47 + 8669527 = 8669574
61 + 8669513 = 8669574
73 + 8669501 = 8669574
97 + 8669477 = 8669574
127 + 8669447 = 8669574
131 + 8669443 = 8669574
157 + 8669417 = 8669574

Showing the first eight; more decompositions exist.
