Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511198, here are decompositions:

5 + 511193 = 511198
29 + 511169 = 511198
47 + 511151 = 511198
89 + 511109 = 511198
137 + 511061 = 511198
179 + 511019 = 511198
197 + 511001 = 511198
257 + 510941 = 511198

Showing the first eight; more decompositions exist.
