Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491148, here are decompositions:

11 + 491137 = 491148
19 + 491129 = 491148
67 + 491081 = 491148
89 + 491059 = 491148
107 + 491041 = 491148
109 + 491039 = 491148
157 + 490991 = 491148
179 + 490969 = 491148

Showing the first eight; more decompositions exist.
