Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500256, here are decompositions:

7 + 500249 = 500256
17 + 500239 = 500256
19 + 500237 = 500256
23 + 500233 = 500256
47 + 500209 = 500256
59 + 500197 = 500256
79 + 500177 = 500256
83 + 500173 = 500256

Showing the first eight; more decompositions exist.
