Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520286, here are decompositions:

7 + 520279 = 520286
73 + 520213 = 520286
157 + 520129 = 520286
163 + 520123 = 520286
223 + 520063 = 520286
367 + 519919 = 520286
379 + 519907 = 520286
397 + 519889 = 520286

Showing the first eight; more decompositions exist.
