Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491072, here are decompositions:

13 + 491059 = 491072
31 + 491041 = 491072
79 + 490993 = 491072
103 + 490969 = 491072
151 + 490921 = 491072
181 + 490891 = 491072
223 + 490849 = 491072
331 + 490741 = 491072

Showing the first eight; more decompositions exist.
