Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523668, here are decompositions:

11 + 523657 = 523668
29 + 523639 = 523668
31 + 523637 = 523668
37 + 523631 = 523668
71 + 523597 = 523668
97 + 523571 = 523668
127 + 523541 = 523668
149 + 523519 = 523668

Showing the first eight; more decompositions exist.
