Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021276, here are decompositions:

5 + 1021271 = 1021276
17 + 1021259 = 1021276
23 + 1021253 = 1021276
59 + 1021217 = 1021276
149 + 1021127 = 1021276
233 + 1021043 = 1021276
257 + 1021019 = 1021276
317 + 1020959 = 1021276

Showing the first eight; more decompositions exist.
