Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523938, here are decompositions:

11 + 523927 = 523938
31 + 523907 = 523938
61 + 523877 = 523938
71 + 523867 = 523938
109 + 523829 = 523938
137 + 523801 = 523938
167 + 523771 = 523938
179 + 523759 = 523938

Showing the first eight; more decompositions exist.
