Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499100, here are decompositions:

37 + 499063 = 499100
61 + 499039 = 499100
67 + 499033 = 499100
73 + 499027 = 499100
79 + 499021 = 499100
127 + 498973 = 499100
139 + 498961 = 499100
163 + 498937 = 499100

Showing the first eight; more decompositions exist.
