Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512178, here are decompositions:

11 + 512167 = 512178
31 + 512147 = 512178
41 + 512137 = 512178
131 + 512047 = 512178
157 + 512021 = 512178
167 + 512011 = 512178
181 + 511997 = 512178
239 + 511939 = 512178

Showing the first eight; more decompositions exist.
