Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519872, here are decompositions:

79 + 519793 = 519872
103 + 519769 = 519872
139 + 519733 = 519872
181 + 519691 = 519872
229 + 519643 = 519872
349 + 519523 = 519872
373 + 519499 = 519872
439 + 519433 = 519872

Showing the first eight; more decompositions exist.
