Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501982, here are decompositions:

11 + 501971 = 501982
29 + 501953 = 501982
71 + 501911 = 501982
179 + 501803 = 501982
251 + 501731 = 501982
263 + 501719 = 501982
281 + 501701 = 501982
359 + 501623 = 501982

Showing the first eight; more decompositions exist.
