Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500872, here are decompositions:

11 + 500861 = 500872
41 + 500831 = 500872
131 + 500741 = 500872
149 + 500723 = 500872
173 + 500699 = 500872
179 + 500693 = 500872
269 + 500603 = 500872
293 + 500579 = 500872

Showing the first eight; more decompositions exist.
