Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500538, here are decompositions:

11 + 500527 = 500538
19 + 500519 = 500538
29 + 500509 = 500538
37 + 500501 = 500538
67 + 500471 = 500538
79 + 500459 = 500538
107 + 500431 = 500538
149 + 500389 = 500538

Showing the first eight; more decompositions exist.
