Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491732, here are decompositions:

13 + 491719 = 491732
79 + 491653 = 491732
139 + 491593 = 491732
151 + 491581 = 491732
193 + 491539 = 491732
229 + 491503 = 491732
271 + 491461 = 491732
379 + 491353 = 491732

Showing the first eight; more decompositions exist.
