Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523990, here are decompositions:

3 + 523987 = 523990
41 + 523949 = 523990
53 + 523937 = 523990
83 + 523907 = 523990
113 + 523877 = 523990
197 + 523793 = 523990
227 + 523763 = 523990
317 + 523673 = 523990

Showing the first eight; more decompositions exist.
