Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491426, here are decompositions:

3 + 491423 = 491426
73 + 491353 = 491426
97 + 491329 = 491426
127 + 491299 = 491426
277 + 491149 = 491426
367 + 491059 = 491426
433 + 490993 = 491426
457 + 490969 = 491426

Showing the first eight; more decompositions exist.
