Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519228, here are decompositions:

11 + 519217 = 519228
67 + 519161 = 519228
97 + 519131 = 519228
107 + 519121 = 519228
109 + 519119 = 519228
131 + 519097 = 519228
137 + 519091 = 519228
139 + 519089 = 519228

Showing the first eight; more decompositions exist.
