Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491396, here are decompositions:

19 + 491377 = 491396
43 + 491353 = 491396
67 + 491329 = 491396
97 + 491299 = 491396
229 + 491167 = 491396
313 + 491083 = 491396
337 + 491059 = 491396
439 + 490957 = 491396

Showing the first eight; more decompositions exist.
