Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523656, here are decompositions:

17 + 523639 = 523656
19 + 523637 = 523656
53 + 523603 = 523656
59 + 523597 = 523656
79 + 523577 = 523656
83 + 523573 = 523656
103 + 523553 = 523656
113 + 523543 = 523656

Showing the first eight; more decompositions exist.
