Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491474, here are decompositions:

13 + 491461 = 491474
97 + 491377 = 491474
103 + 491371 = 491474
223 + 491251 = 491474
307 + 491167 = 491474
337 + 491137 = 491474
433 + 491041 = 491474
523 + 490951 = 491474

Showing the first eight; more decompositions exist.
