Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511376, here are decompositions:

43 + 511333 = 511376
79 + 511297 = 511376
97 + 511279 = 511376
139 + 511237 = 511376
163 + 511213 = 511376
199 + 511177 = 511376
223 + 511153 = 511376
337 + 511039 = 511376

Showing the first eight; more decompositions exist.
