Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512740, here are decompositions:

23 + 512717 = 512740
29 + 512711 = 512740
83 + 512657 = 512740
131 + 512609 = 512740
149 + 512591 = 512740
167 + 512573 = 512740
197 + 512543 = 512740
233 + 512507 = 512740

Showing the first eight; more decompositions exist.
