Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491154, here are decompositions:

5 + 491149 = 491154
17 + 491137 = 491154
71 + 491083 = 491154
73 + 491081 = 491154
113 + 491041 = 491154
151 + 491003 = 491154
163 + 490991 = 491154
197 + 490957 = 491154

Showing the first eight; more decompositions exist.
