Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499406, here are decompositions:

3 + 499403 = 499406
43 + 499363 = 499406
79 + 499327 = 499406
97 + 499309 = 499406
139 + 499267 = 499406
223 + 499183 = 499406
277 + 499129 = 499406
307 + 499099 = 499406

Showing the first eight; more decompositions exist.
