Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531276, here are decompositions:

13 + 531263 = 531276
23 + 531253 = 531276
37 + 531239 = 531276
47 + 531229 = 531276
73 + 531203 = 531276
79 + 531197 = 531276
103 + 531173 = 531276
107 + 531169 = 531276

Showing the first eight; more decompositions exist.
