Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499490, here are decompositions:

7 + 499483 = 499490
31 + 499459 = 499490
67 + 499423 = 499490
127 + 499363 = 499490
163 + 499327 = 499490
181 + 499309 = 499490
223 + 499267 = 499490
307 + 499183 = 499490

Showing the first eight; more decompositions exist.
