Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499478, here are decompositions:

19 + 499459 = 499478
151 + 499327 = 499478
157 + 499321 = 499478
211 + 499267 = 499478
337 + 499141 = 499478
349 + 499129 = 499478
379 + 499099 = 499478
439 + 499039 = 499478

Showing the first eight; more decompositions exist.
