Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509164, here are decompositions:

17 + 509147 = 509164
41 + 509123 = 509164
101 + 509063 = 509164
137 + 509027 = 509164
191 + 508973 = 509164
233 + 508931 = 509164
251 + 508913 = 509164
263 + 508901 = 509164

Showing the first eight; more decompositions exist.
