Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511238, here are decompositions:

37 + 511201 = 511238
61 + 511177 = 511238
67 + 511171 = 511238
127 + 511111 = 511238
151 + 511087 = 511238
181 + 511057 = 511238
199 + 511039 = 511238
307 + 510931 = 511238

Showing the first eight; more decompositions exist.
