Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509200, here are decompositions:

53 + 509147 = 509200
113 + 509087 = 509200
137 + 509063 = 509200
173 + 509027 = 509200
227 + 508973 = 509200
239 + 508961 = 509200
257 + 508943 = 509200
269 + 508931 = 509200

Showing the first eight; more decompositions exist.
