Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531564, here are decompositions:

13 + 531551 = 531564
17 + 531547 = 531564
43 + 531521 = 531564
67 + 531497 = 531564
83 + 531481 = 531564
107 + 531457 = 531564
181 + 531383 = 531564
211 + 531353 = 531564

Showing the first eight; more decompositions exist.
