Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523216, here are decompositions:

3 + 523213 = 523216
47 + 523169 = 523216
107 + 523109 = 523216
167 + 523049 = 523216
227 + 522989 = 523216
257 + 522959 = 523216
269 + 522947 = 523216
359 + 522857 = 523216

Showing the first eight; more decompositions exist.
