Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021266, here are decompositions:

5 + 1021261 = 1021266
7 + 1021259 = 1021266
13 + 1021253 = 1021266
23 + 1021243 = 1021266
67 + 1021199 = 1021266
83 + 1021183 = 1021266
107 + 1021159 = 1021266
109 + 1021157 = 1021266

Showing the first eight; more decompositions exist.
