Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491262, here are decompositions:

11 + 491251 = 491262
43 + 491219 = 491262
61 + 491201 = 491262
103 + 491159 = 491262
113 + 491149 = 491262
179 + 491083 = 491262
181 + 491081 = 491262
223 + 491039 = 491262

Showing the first eight; more decompositions exist.
