Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021694, here are decompositions:

31 + 1021663 = 1021694
43 + 1021651 = 1021694
67 + 1021627 = 1021694
73 + 1021621 = 1021694
211 + 1021483 = 1021694
277 + 1021417 = 1021694
307 + 1021387 = 1021694
313 + 1021381 = 1021694

Showing the first eight; more decompositions exist.
