Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531364, here are decompositions:

5 + 531359 = 531364
11 + 531353 = 531364
17 + 531347 = 531364
83 + 531281 = 531364
101 + 531263 = 531364
167 + 531197 = 531364
191 + 531173 = 531364
263 + 531101 = 531364

Showing the first eight; more decompositions exist.
