Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499242, here are decompositions:

13 + 499229 = 499242
31 + 499211 = 499242
53 + 499189 = 499242
59 + 499183 = 499242
61 + 499181 = 499242
83 + 499159 = 499242
101 + 499141 = 499242
103 + 499139 = 499242

Showing the first eight; more decompositions exist.
