Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503918, here are decompositions:

7 + 503911 = 503918
61 + 503857 = 503918
67 + 503851 = 503918
97 + 503821 = 503918
127 + 503791 = 503918
139 + 503779 = 503918
211 + 503707 = 503918
271 + 503647 = 503918

Showing the first eight; more decompositions exist.
