Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8572, here are decompositions:

29 + 8543 = 8572
59 + 8513 = 8572
71 + 8501 = 8572
149 + 8423 = 8572
281 + 8291 = 8572
353 + 8219 = 8572
401 + 8171 = 8572
449 + 8123 = 8572

Showing the first eight; more decompositions exist.
