Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531996, here are decompositions:

7 + 531989 = 531996
13 + 531983 = 531996
19 + 531977 = 531996
139 + 531857 = 531996
149 + 531847 = 531996
163 + 531833 = 531996
173 + 531823 = 531996
197 + 531799 = 531996

Showing the first eight; more decompositions exist.
