Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021494, here are decompositions:

7 + 1021487 = 1021494
11 + 1021483 = 1021494
31 + 1021463 = 1021494
37 + 1021457 = 1021494
53 + 1021441 = 1021494
107 + 1021387 = 1021494
113 + 1021381 = 1021494
127 + 1021367 = 1021494

Showing the first eight; more decompositions exist.
