Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531298, here are decompositions:

11 + 531287 = 531298
17 + 531281 = 531298
59 + 531239 = 531298
101 + 531197 = 531298
197 + 531101 = 531298
227 + 531071 = 531298
281 + 531017 = 531298
401 + 530897 = 531298

Showing the first eight; more decompositions exist.
