Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021272, here are decompositions:

11 + 1021261 = 1021272
13 + 1021259 = 1021272
19 + 1021253 = 1021272
29 + 1021243 = 1021272
73 + 1021199 = 1021272
89 + 1021183 = 1021272
113 + 1021159 = 1021272
149 + 1021123 = 1021272

Showing the first eight; more decompositions exist.
