Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512436, here are decompositions:

7 + 512429 = 512436
17 + 512419 = 512436
47 + 512389 = 512436
83 + 512353 = 512436
103 + 512333 = 512436
149 + 512287 = 512436
167 + 512269 = 512436
229 + 512207 = 512436

Showing the first eight; more decompositions exist.
