Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519550, here are decompositions:

11 + 519539 = 519550
23 + 519527 = 519550
29 + 519521 = 519550
41 + 519509 = 519550
137 + 519413 = 519550
167 + 519383 = 519550
179 + 519371 = 519550
191 + 519359 = 519550

Showing the first eight; more decompositions exist.
