Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520930, here are decompositions:

17 + 520913 = 520930
41 + 520889 = 520930
89 + 520841 = 520930
167 + 520763 = 520930
227 + 520703 = 520930
239 + 520691 = 520930
251 + 520679 = 520930
281 + 520649 = 520930

Showing the first eight; more decompositions exist.
