Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500138, here are decompositions:

19 + 500119 = 500138
31 + 500107 = 500138
97 + 500041 = 500138
109 + 500029 = 500138
181 + 499957 = 500138
211 + 499927 = 500138
241 + 499897 = 500138
337 + 499801 = 500138

Showing the first eight; more decompositions exist.
