Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491354, here are decompositions:

13 + 491341 = 491354
103 + 491251 = 491354
271 + 491083 = 491354
313 + 491041 = 491354
397 + 490957 = 491354
433 + 490921 = 491354
463 + 490891 = 491354
571 + 490783 = 491354

Showing the first eight; more decompositions exist.
