Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021146, here are decompositions:

17 + 1021129 = 1021146
19 + 1021127 = 1021146
23 + 1021123 = 1021146
53 + 1021093 = 1021146
59 + 1021087 = 1021146
73 + 1021073 = 1021146
79 + 1021067 = 1021146
103 + 1021043 = 1021146

Showing the first eight; more decompositions exist.
