Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531504, here are decompositions:

7 + 531497 = 531504
23 + 531481 = 531504
47 + 531457 = 531504
151 + 531353 = 531504
157 + 531347 = 531504
167 + 531337 = 531504
173 + 531331 = 531504
223 + 531281 = 531504

Showing the first eight; more decompositions exist.
