Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512008, here are decompositions:

11 + 511997 = 512008
17 + 511991 = 512008
47 + 511961 = 512008
149 + 511859 = 512008
197 + 511811 = 512008
251 + 511757 = 512008
317 + 511691 = 512008
449 + 511559 = 512008

Showing the first eight; more decompositions exist.
