Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021284, here are decompositions:

13 + 1021271 = 1021284
23 + 1021261 = 1021284
31 + 1021253 = 1021284
41 + 1021243 = 1021284
67 + 1021217 = 1021284
101 + 1021183 = 1021284
127 + 1021157 = 1021284
157 + 1021127 = 1021284

Showing the first eight; more decompositions exist.
