Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531548, here are decompositions:

67 + 531481 = 531548
211 + 531337 = 531548
379 + 531169 = 531548
571 + 530977 = 531548
601 + 530947 = 531548
691 + 530857 = 531548
751 + 530797 = 531548
907 + 530641 = 531548

Showing the first eight; more decompositions exist.
