Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511344, here are decompositions:

7 + 511337 = 511344
11 + 511333 = 511344
17 + 511327 = 511344
47 + 511297 = 511344
83 + 511261 = 511344
101 + 511243 = 511344
107 + 511237 = 511344
131 + 511213 = 511344

Showing the first eight; more decompositions exist.
