Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523720, here are decompositions:

3 + 523717 = 523720
47 + 523673 = 523720
53 + 523667 = 523720
83 + 523637 = 523720
89 + 523631 = 523720
149 + 523571 = 523720
167 + 523553 = 523720
179 + 523541 = 523720

Showing the first eight; more decompositions exist.
