Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3564, here are decompositions:

5 + 3559 = 3564
7 + 3557 = 3564
17 + 3547 = 3564
23 + 3541 = 3564
31 + 3533 = 3564
37 + 3527 = 3564
47 + 3517 = 3564
53 + 3511 = 3564

Showing the first eight; more decompositions exist.
