Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491112, here are decompositions:

29 + 491083 = 491112
31 + 491081 = 491112
53 + 491059 = 491112
71 + 491041 = 491112
73 + 491039 = 491112
109 + 491003 = 491112
163 + 490949 = 491112
191 + 490921 = 491112

Showing the first eight; more decompositions exist.
