Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491772, here are decompositions:

41 + 491731 = 491772
53 + 491719 = 491772
103 + 491669 = 491772
139 + 491633 = 491772
179 + 491593 = 491772
181 + 491591 = 491772
191 + 491581 = 491772
233 + 491539 = 491772

Showing the first eight; more decompositions exist.
