Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511218, here are decompositions:

5 + 511213 = 511218
7 + 511211 = 511218
17 + 511201 = 511218
41 + 511177 = 511218
47 + 511171 = 511218
67 + 511151 = 511218
107 + 511111 = 511218
109 + 511109 = 511218

Showing the first eight; more decompositions exist.
