Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500678, here are decompositions:

7 + 500671 = 500678
151 + 500527 = 500678
337 + 500341 = 500678
379 + 500299 = 500678
421 + 500257 = 500678
439 + 500239 = 500678
499 + 500179 = 500678
571 + 500107 = 500678

Showing the first eight; more decompositions exist.
