Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509208, here are decompositions:

5 + 509203 = 509208
59 + 509149 = 509208
61 + 509147 = 509208
71 + 509137 = 509208
107 + 509101 = 509208
137 + 509071 = 509208
181 + 509027 = 509208
239 + 508969 = 509208

Showing the first eight; more decompositions exist.
