Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499042, here are decompositions:

3 + 499039 = 499042
53 + 498989 = 499042
239 + 498803 = 499042
251 + 498791 = 499042
263 + 498779 = 499042
281 + 498761 = 499042
293 + 498749 = 499042
353 + 498689 = 499042

Showing the first eight; more decompositions exist.
