Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491058, here are decompositions:

17 + 491041 = 491058
19 + 491039 = 491058
67 + 490991 = 491058
89 + 490969 = 491058
101 + 490957 = 491058
107 + 490951 = 491058
109 + 490949 = 491058
131 + 490927 = 491058

Showing the first eight; more decompositions exist.
