Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491882, here are decompositions:

31 + 491851 = 491882
109 + 491773 = 491882
151 + 491731 = 491882
163 + 491719 = 491882
229 + 491653 = 491882
271 + 491611 = 491882
379 + 491503 = 491882
421 + 491461 = 491882

Showing the first eight; more decompositions exist.
