Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523660, here are decompositions:

3 + 523657 = 523660
23 + 523637 = 523660
29 + 523631 = 523660
83 + 523577 = 523660
89 + 523571 = 523660
107 + 523553 = 523660
149 + 523511 = 523660
167 + 523493 = 523660

Showing the first eight; more decompositions exist.
