Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512450, here are decompositions:

7 + 512443 = 512450
31 + 512419 = 512450
61 + 512389 = 512450
97 + 512353 = 512450
139 + 512311 = 512450
163 + 512287 = 512450
181 + 512269 = 512450
199 + 512251 = 512450

Showing the first eight; more decompositions exist.
