Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499072, here are decompositions:

5 + 499067 = 499072
83 + 498989 = 499072
149 + 498923 = 499072
191 + 498881 = 499072
239 + 498833 = 499072
269 + 498803 = 499072
281 + 498791 = 499072
293 + 498779 = 499072

Showing the first eight; more decompositions exist.
