Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520358, here are decompositions:

19 + 520339 = 520358
61 + 520297 = 520358
67 + 520291 = 520358
79 + 520279 = 520358
229 + 520129 = 520358
337 + 520021 = 520358
439 + 519919 = 520358
541 + 519817 = 520358

Showing the first eight; more decompositions exist.
