Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531984, here are decompositions:

7 + 531977 = 531984
73 + 531911 = 531984
83 + 531901 = 531984
107 + 531877 = 531984
113 + 531871 = 531984
127 + 531857 = 531984
137 + 531847 = 531984
151 + 531833 = 531984

Showing the first eight; more decompositions exist.
