Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519620, here are decompositions:

43 + 519577 = 519620
67 + 519553 = 519620
97 + 519523 = 519620
163 + 519457 = 519620
193 + 519427 = 519620
229 + 519391 = 519620
271 + 519349 = 519620
313 + 519307 = 519620

Showing the first eight; more decompositions exist.
