Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018922, here are decompositions:

19 + 1018903 = 1018922
43 + 1018879 = 1018922
109 + 1018813 = 1018922
193 + 1018729 = 1018922
211 + 1018711 = 1018922
271 + 1018651 = 1018922
379 + 1018543 = 1018922
409 + 1018513 = 1018922

Showing the first eight; more decompositions exist.
