Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491754, here are decompositions:

7 + 491747 = 491754
17 + 491737 = 491754
23 + 491731 = 491754
47 + 491707 = 491754
101 + 491653 = 491754
103 + 491651 = 491754
127 + 491627 = 491754
163 + 491591 = 491754

Showing the first eight; more decompositions exist.
