Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512188, here are decompositions:

41 + 512147 = 512188
167 + 512021 = 512188
179 + 512009 = 512188
191 + 511997 = 512188
197 + 511991 = 512188
227 + 511961 = 512188
401 + 511787 = 512188
431 + 511757 = 512188

Showing the first eight; more decompositions exist.
