Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021340, here are decompositions:

7 + 1021333 = 1021340
13 + 1021327 = 1021340
37 + 1021303 = 1021340
43 + 1021297 = 1021340
79 + 1021261 = 1021340
97 + 1021243 = 1021340
157 + 1021183 = 1021340
181 + 1021159 = 1021340

Showing the first eight; more decompositions exist.
