Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018992, here are decompositions:

5 + 1018987 = 1018992
11 + 1018981 = 1018992
43 + 1018949 = 1018992
61 + 1018931 = 1018992
89 + 1018903 = 1018992
103 + 1018889 = 1018992
113 + 1018879 = 1018992
179 + 1018813 = 1018992

Showing the first eight; more decompositions exist.
