Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500508, here are decompositions:

7 + 500501 = 500508
37 + 500471 = 500508
139 + 500369 = 500508
167 + 500341 = 500508
191 + 500317 = 500508
251 + 500257 = 500508
269 + 500239 = 500508
271 + 500237 = 500508

Showing the first eight; more decompositions exist.
