Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519572, here are decompositions:

19 + 519553 = 519572
73 + 519499 = 519572
139 + 519433 = 519572
181 + 519391 = 519572
199 + 519373 = 519572
223 + 519349 = 519572
271 + 519301 = 519572
379 + 519193 = 519572

Showing the first eight; more decompositions exist.
