Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491348, here are decompositions:

7 + 491341 = 491348
19 + 491329 = 491348
97 + 491251 = 491348
181 + 491167 = 491348
199 + 491149 = 491348
211 + 491137 = 491348
307 + 491041 = 491348
379 + 490969 = 491348

Showing the first eight; more decompositions exist.
