Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491762, here are decompositions:

31 + 491731 = 491762
43 + 491719 = 491762
109 + 491653 = 491762
151 + 491611 = 491762
181 + 491581 = 491762
223 + 491539 = 491762
409 + 491353 = 491762
421 + 491341 = 491762

Showing the first eight; more decompositions exist.
