Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491954, here are decompositions:

3 + 491951 = 491954
31 + 491923 = 491954
97 + 491857 = 491954
103 + 491851 = 491954
157 + 491797 = 491954
181 + 491773 = 491954
223 + 491731 = 491954
277 + 491677 = 491954

Showing the first eight; more decompositions exist.
