Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021084, here are decompositions:

3 + 1021081 = 1021084
11 + 1021073 = 1021084
17 + 1021067 = 1021084
41 + 1021043 = 1021084
83 + 1021001 = 1021084
107 + 1020977 = 1021084
191 + 1020893 = 1021084
257 + 1020827 = 1021084

Showing the first eight; more decompositions exist.
