Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531582, here are decompositions:

11 + 531571 = 531582
13 + 531569 = 531582
31 + 531551 = 531582
61 + 531521 = 531582
101 + 531481 = 531582
199 + 531383 = 531582
223 + 531359 = 531582
229 + 531353 = 531582

Showing the first eight; more decompositions exist.
