Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531676, here are decompositions:

3 + 531673 = 531676
53 + 531623 = 531676
107 + 531569 = 531676
179 + 531497 = 531676
293 + 531383 = 531676
317 + 531359 = 531676
389 + 531287 = 531676
479 + 531197 = 531676

Showing the first eight; more decompositions exist.
