Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520166, here are decompositions:

37 + 520129 = 520166
43 + 520123 = 520166
103 + 520063 = 520166
223 + 519943 = 520166
277 + 519889 = 520166
349 + 519817 = 520166
373 + 519793 = 520166
379 + 519787 = 520166

Showing the first eight; more decompositions exist.
