Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519178, here are decompositions:

17 + 519161 = 519178
47 + 519131 = 519178
59 + 519119 = 519178
71 + 519107 = 519178
89 + 519089 = 519178
167 + 519011 = 519178
197 + 518981 = 519178
311 + 518867 = 519178

Showing the first eight; more decompositions exist.
