Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71564, here are decompositions:

13 + 71551 = 71564
37 + 71527 = 71564
61 + 71503 = 71564
127 + 71437 = 71564
151 + 71413 = 71564
211 + 71353 = 71564
223 + 71341 = 71564
271 + 71293 = 71564

Showing the first eight; more decompositions exist.
