Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513268, here are decompositions:

11 + 513257 = 513268
29 + 513239 = 513268
101 + 513167 = 513268
131 + 513137 = 513268
137 + 513131 = 513268
167 + 513101 = 513268
227 + 513041 = 513268
251 + 513017 = 513268

Showing the first eight; more decompositions exist.
