Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491744, here are decompositions:

7 + 491737 = 491744
13 + 491731 = 491744
37 + 491707 = 491744
67 + 491677 = 491744
151 + 491593 = 491744
163 + 491581 = 491744
241 + 491503 = 491744
283 + 491461 = 491744

Showing the first eight; more decompositions exist.
