Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499398, here are decompositions:

7 + 499391 = 499398
37 + 499361 = 499398
71 + 499327 = 499398
89 + 499309 = 499398
131 + 499267 = 499398
239 + 499159 = 499398
241 + 499157 = 499398
257 + 499141 = 499398

Showing the first eight; more decompositions exist.
