Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021392, here are decompositions:

5 + 1021387 = 1021392
11 + 1021381 = 1021392
19 + 1021373 = 1021392
23 + 1021369 = 1021392
59 + 1021333 = 1021392
61 + 1021331 = 1021392
89 + 1021303 = 1021392
101 + 1021291 = 1021392

Showing the first eight; more decompositions exist.
