Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520064, here are decompositions:

43 + 520021 = 520064
67 + 519997 = 520064
157 + 519907 = 520064
271 + 519793 = 520064
277 + 519787 = 520064
331 + 519733 = 520064
373 + 519691 = 520064
397 + 519667 = 520064

Showing the first eight; more decompositions exist.
