Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499130, here are decompositions:

3 + 499127 = 499130
13 + 499117 = 499130
31 + 499099 = 499130
67 + 499063 = 499130
97 + 499033 = 499130
103 + 499027 = 499130
109 + 499021 = 499130
157 + 498973 = 499130

Showing the first eight; more decompositions exist.
