Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511516, here are decompositions:

29 + 511487 = 511516
53 + 511463 = 511516
59 + 511457 = 511516
107 + 511409 = 511516
179 + 511337 = 511516
227 + 511289 = 511516
293 + 511223 = 511516
347 + 511169 = 511516

Showing the first eight; more decompositions exist.
