Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511340, here are decompositions:

3 + 511337 = 511340
7 + 511333 = 511340
13 + 511327 = 511340
43 + 511297 = 511340
61 + 511279 = 511340
79 + 511261 = 511340
97 + 511243 = 511340
103 + 511237 = 511340

Showing the first eight; more decompositions exist.
