Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491082, here are decompositions:

23 + 491059 = 491082
41 + 491041 = 491082
43 + 491039 = 491082
79 + 491003 = 491082
89 + 490993 = 491082
113 + 490969 = 491082
131 + 490951 = 491082
191 + 490891 = 491082

Showing the first eight; more decompositions exist.
