Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021290, here are decompositions:

7 + 1021283 = 1021290
19 + 1021271 = 1021290
29 + 1021261 = 1021290
31 + 1021259 = 1021290
37 + 1021253 = 1021290
47 + 1021243 = 1021290
73 + 1021217 = 1021290
107 + 1021183 = 1021290

Showing the first eight; more decompositions exist.
