Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491952, here are decompositions:

29 + 491923 = 491952
53 + 491899 = 491952
79 + 491873 = 491952
101 + 491851 = 491952
163 + 491789 = 491952
179 + 491773 = 491952
233 + 491719 = 491952
283 + 491669 = 491952

Showing the first eight; more decompositions exist.
