Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519148, here are decompositions:

17 + 519131 = 519148
29 + 519119 = 519148
41 + 519107 = 519148
59 + 519089 = 519148
137 + 519011 = 519148
167 + 518981 = 519148
281 + 518867 = 519148
317 + 518831 = 519148

Showing the first eight; more decompositions exist.
