Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018892, here are decompositions:

3 + 1018889 = 1018892
13 + 1018879 = 1018892
19 + 1018873 = 1018892
79 + 1018813 = 1018892
103 + 1018789 = 1018892
163 + 1018729 = 1018892
181 + 1018711 = 1018892
223 + 1018669 = 1018892

Showing the first eight; more decompositions exist.
