Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499642, here are decompositions:

5 + 499637 = 499642
41 + 499601 = 499642
71 + 499571 = 499642
83 + 499559 = 499642
149 + 499493 = 499642
239 + 499403 = 499642
251 + 499391 = 499642
281 + 499361 = 499642

Showing the first eight; more decompositions exist.
