Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501860, here are decompositions:

19 + 501841 = 501860
31 + 501829 = 501860
43 + 501817 = 501860
157 + 501703 = 501860
223 + 501637 = 501860
283 + 501577 = 501860
349 + 501511 = 501860
367 + 501493 = 501860

Showing the first eight; more decompositions exist.
