Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499646, here are decompositions:

13 + 499633 = 499646
97 + 499549 = 499646
127 + 499519 = 499646
139 + 499507 = 499646
163 + 499483 = 499646
223 + 499423 = 499646
283 + 499363 = 499646
337 + 499309 = 499646

Showing the first eight; more decompositions exist.
