Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491366, here are decompositions:

13 + 491353 = 491366
37 + 491329 = 491366
67 + 491299 = 491366
199 + 491167 = 491366
229 + 491137 = 491366
283 + 491083 = 491366
307 + 491059 = 491366
373 + 490993 = 491366

Showing the first eight; more decompositions exist.
