Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8564, here are decompositions:

37 + 8527 = 8564
43 + 8521 = 8564
97 + 8467 = 8564
103 + 8461 = 8564
211 + 8353 = 8564
271 + 8293 = 8564
277 + 8287 = 8564
331 + 8233 = 8564

Showing the first eight; more decompositions exist.
