Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531948, here are decompositions:

29 + 531919 = 531948
37 + 531911 = 531948
47 + 531901 = 531948
71 + 531877 = 531948
101 + 531847 = 531948
107 + 531841 = 531948
127 + 531821 = 531948
149 + 531799 = 531948

Showing the first eight; more decompositions exist.
