Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520256, here are decompositions:

43 + 520213 = 520256
127 + 520129 = 520256
193 + 520063 = 520256
313 + 519943 = 520256
337 + 519919 = 520256
349 + 519907 = 520256
367 + 519889 = 520256
439 + 519817 = 520256

Showing the first eight; more decompositions exist.
