Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520872, here are decompositions:

5 + 520867 = 520872
19 + 520853 = 520872
31 + 520841 = 520872
59 + 520813 = 520872
109 + 520763 = 520872
113 + 520759 = 520872
151 + 520721 = 520872
173 + 520699 = 520872

Showing the first eight; more decompositions exist.
