Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491948, here are decompositions:

97 + 491851 = 491948
151 + 491797 = 491948
211 + 491737 = 491948
229 + 491719 = 491948
241 + 491707 = 491948
271 + 491677 = 491948
337 + 491611 = 491948
367 + 491581 = 491948

Showing the first eight; more decompositions exist.
