Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021766, here are decompositions:

7 + 1021759 = 1021766
13 + 1021753 = 1021766
19 + 1021747 = 1021766
103 + 1021663 = 1021766
139 + 1021627 = 1021766
283 + 1021483 = 1021766
337 + 1021429 = 1021766
349 + 1021417 = 1021766

Showing the first eight; more decompositions exist.
