Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499146, here are decompositions:

5 + 499141 = 499146
7 + 499139 = 499146
13 + 499133 = 499146
17 + 499129 = 499146
19 + 499127 = 499146
29 + 499117 = 499146
47 + 499099 = 499146
79 + 499067 = 499146

Showing the first eight; more decompositions exist.
