Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491552, here are decompositions:

13 + 491539 = 491552
181 + 491371 = 491552
199 + 491353 = 491552
211 + 491341 = 491552
223 + 491329 = 491552
601 + 490951 = 491552
631 + 490921 = 491552
661 + 490891 = 491552

Showing the first eight; more decompositions exist.
