Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519448, here are decompositions:

89 + 519359 = 519448
179 + 519269 = 519448
191 + 519257 = 519448
317 + 519131 = 519448
359 + 519089 = 519448
467 + 518981 = 519448
617 + 518831 = 519448
641 + 518807 = 519448

Showing the first eight; more decompositions exist.
