Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520860, here are decompositions:

7 + 520853 = 520860
19 + 520841 = 520860
23 + 520837 = 520860
47 + 520813 = 520860
73 + 520787 = 520860
97 + 520763 = 520860
101 + 520759 = 520860
113 + 520747 = 520860

Showing the first eight; more decompositions exist.
