Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520908, here are decompositions:

19 + 520889 = 520908
41 + 520867 = 520908
67 + 520841 = 520908
71 + 520837 = 520908
149 + 520759 = 520908
191 + 520717 = 520908
229 + 520679 = 520908
277 + 520631 = 520908

Showing the first eight; more decompositions exist.
