Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491892, here are decompositions:

19 + 491873 = 491892
41 + 491851 = 491892
59 + 491833 = 491892
73 + 491819 = 491892
103 + 491789 = 491892
109 + 491783 = 491892
173 + 491719 = 491892
223 + 491669 = 491892

Showing the first eight; more decompositions exist.
