Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531592, here are decompositions:

3 + 531589 = 531592
11 + 531581 = 531592
23 + 531569 = 531592
41 + 531551 = 531592
71 + 531521 = 531592
233 + 531359 = 531592
239 + 531353 = 531592
293 + 531299 = 531592

Showing the first eight; more decompositions exist.
