Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527988, here are decompositions:

5 + 527983 = 527988
7 + 527981 = 527988
47 + 527941 = 527988
59 + 527929 = 527988
67 + 527921 = 527988
79 + 527909 = 527988
107 + 527881 = 527988
137 + 527851 = 527988

Showing the first eight; more decompositions exist.
