Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491092, here are decompositions:

11 + 491081 = 491092
53 + 491039 = 491092
89 + 491003 = 491092
101 + 490991 = 491092
179 + 490913 = 491092
233 + 490859 = 491092
263 + 490829 = 491092
359 + 490733 = 491092

Showing the first eight; more decompositions exist.
