Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511308, here are decompositions:

11 + 511297 = 511308
19 + 511289 = 511308
29 + 511279 = 511308
47 + 511261 = 511308
71 + 511237 = 511308
97 + 511211 = 511308
107 + 511201 = 511308
131 + 511177 = 511308

Showing the first eight; more decompositions exist.
