Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520942, here are decompositions:

29 + 520913 = 520942
53 + 520889 = 520942
89 + 520853 = 520942
101 + 520841 = 520942
179 + 520763 = 520942
239 + 520703 = 520942
251 + 520691 = 520942
263 + 520679 = 520942

Showing the first eight; more decompositions exist.
