Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8574, here are decompositions:

11 + 8563 = 8574
31 + 8543 = 8574
37 + 8537 = 8574
47 + 8527 = 8574
53 + 8521 = 8574
61 + 8513 = 8574
73 + 8501 = 8574
107 + 8467 = 8574

Showing the first eight; more decompositions exist.
