Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501864, here are decompositions:

23 + 501841 = 501864
37 + 501827 = 501864
43 + 501821 = 501864
47 + 501817 = 501864
61 + 501803 = 501864
157 + 501707 = 501864
163 + 501701 = 501864
173 + 501691 = 501864

Showing the first eight; more decompositions exist.
