Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513448, here are decompositions:

17 + 513431 = 513448
29 + 513419 = 513448
41 + 513407 = 513448
101 + 513347 = 513448
107 + 513341 = 513448
137 + 513311 = 513448
179 + 513269 = 513448
191 + 513257 = 513448

Showing the first eight; more decompositions exist.
