Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511206, here are decompositions:

5 + 511201 = 511206
13 + 511193 = 511206
29 + 511177 = 511206
37 + 511169 = 511206
43 + 511163 = 511206
53 + 511153 = 511206
83 + 511123 = 511206
97 + 511109 = 511206

Showing the first eight; more decompositions exist.
