Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491070, here are decompositions:

11 + 491059 = 491070
29 + 491041 = 491070
31 + 491039 = 491070
67 + 491003 = 491070
79 + 490991 = 491070
101 + 490969 = 491070
103 + 490967 = 491070
113 + 490957 = 491070

Showing the first eight; more decompositions exist.
