Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021042, here are decompositions:

23 + 1021019 = 1021042
41 + 1021001 = 1021042
53 + 1020989 = 1021042
83 + 1020959 = 1021042
149 + 1020893 = 1021042
263 + 1020779 = 1021042
353 + 1020689 = 1021042
359 + 1020683 = 1021042

Showing the first eight; more decompositions exist.
