Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511266, here are decompositions:

5 + 511261 = 511266
23 + 511243 = 511266
29 + 511237 = 511266
43 + 511223 = 511266
53 + 511213 = 511266
73 + 511193 = 511266
89 + 511177 = 511266
97 + 511169 = 511266

Showing the first eight; more decompositions exist.
