Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021282, here are decompositions:

11 + 1021271 = 1021282
23 + 1021259 = 1021282
29 + 1021253 = 1021282
83 + 1021199 = 1021282
191 + 1021091 = 1021282
239 + 1021043 = 1021282
263 + 1021019 = 1021282
281 + 1021001 = 1021282

Showing the first eight; more decompositions exist.
