Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501918, here are decompositions:

7 + 501911 = 501918
29 + 501889 = 501918
89 + 501829 = 501918
97 + 501821 = 501918
101 + 501817 = 501918
139 + 501779 = 501918
149 + 501769 = 501918
199 + 501719 = 501918

Showing the first eight; more decompositions exist.
