Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491124, here are decompositions:

41 + 491083 = 491124
43 + 491081 = 491124
83 + 491041 = 491124
131 + 490993 = 491124
157 + 490967 = 491124
167 + 490957 = 491124
173 + 490951 = 491124
197 + 490927 = 491124

Showing the first eight; more decompositions exist.
