Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500636, here are decompositions:

7 + 500629 = 500636
109 + 500527 = 500636
127 + 500509 = 500636
163 + 500473 = 500636
193 + 500443 = 500636
223 + 500413 = 500636
337 + 500299 = 500636
349 + 500287 = 500636

Showing the first eight; more decompositions exist.
