Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509178, here are decompositions:

29 + 509149 = 509178
31 + 509147 = 509178
41 + 509137 = 509178
107 + 509071 = 509178
151 + 509027 = 509178
191 + 508987 = 509178
227 + 508951 = 509178
269 + 508909 = 509178

Showing the first eight; more decompositions exist.
