Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018994, here are decompositions:

7 + 1018987 = 1018994
13 + 1018981 = 1018994
37 + 1018957 = 1018994
181 + 1018813 = 1018994
283 + 1018711 = 1018994
373 + 1018621 = 1018994
523 + 1018471 = 1018994
547 + 1018447 = 1018994

Showing the first eight; more decompositions exist.
