Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491594, here are decompositions:

3 + 491591 = 491594
13 + 491581 = 491594
67 + 491527 = 491594
97 + 491497 = 491594
223 + 491371 = 491594
241 + 491353 = 491594
457 + 491137 = 491594
601 + 490993 = 491594

Showing the first eight; more decompositions exist.
