Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491726, here are decompositions:

7 + 491719 = 491726
19 + 491707 = 491726
73 + 491653 = 491726
199 + 491527 = 491726
223 + 491503 = 491726
229 + 491497 = 491726
349 + 491377 = 491726
373 + 491353 = 491726

Showing the first eight; more decompositions exist.
