Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499400, here are decompositions:

3 + 499397 = 499400
37 + 499363 = 499400
73 + 499327 = 499400
79 + 499321 = 499400
211 + 499189 = 499400
241 + 499159 = 499400
271 + 499129 = 499400
283 + 499117 = 499400

Showing the first eight; more decompositions exist.
