Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501942, here are decompositions:

11 + 501931 = 501942
31 + 501911 = 501942
53 + 501889 = 501942
79 + 501863 = 501942
101 + 501841 = 501942
113 + 501829 = 501942
139 + 501803 = 501942
163 + 501779 = 501942

Showing the first eight; more decompositions exist.
