Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16564, here are decompositions:

3 + 16561 = 16564
11 + 16553 = 16564
17 + 16547 = 16564
71 + 16493 = 16564
83 + 16481 = 16564
113 + 16451 = 16564
131 + 16433 = 16564
137 + 16427 = 16564

Showing the first eight; more decompositions exist.
