Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512478, here are decompositions:

11 + 512467 = 512478
59 + 512419 = 512478
89 + 512389 = 512478
157 + 512321 = 512478
167 + 512311 = 512478
191 + 512287 = 512478
227 + 512251 = 512478
229 + 512249 = 512478

Showing the first eight; more decompositions exist.
