Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523998, here are decompositions:

11 + 523987 = 523998
29 + 523969 = 523998
61 + 523937 = 523998
71 + 523927 = 523998
131 + 523867 = 523998
151 + 523847 = 523998
197 + 523801 = 523998
227 + 523771 = 523998

Showing the first eight; more decompositions exist.
