Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512426, here are decompositions:

7 + 512419 = 512426
37 + 512389 = 512426
73 + 512353 = 512426
139 + 512287 = 512426
157 + 512269 = 512426
367 + 512059 = 512426
379 + 512047 = 512426
463 + 511963 = 512426

Showing the first eight; more decompositions exist.
