Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501900, here are decompositions:

11 + 501889 = 501900
37 + 501863 = 501900
59 + 501841 = 501900
71 + 501829 = 501900
73 + 501827 = 501900
79 + 501821 = 501900
83 + 501817 = 501900
97 + 501803 = 501900

Showing the first eight; more decompositions exist.
