Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020782, here are decompositions:

3 + 1020779 = 1020782
31 + 1020751 = 1020782
73 + 1020709 = 1020782
151 + 1020631 = 1020782
163 + 1020619 = 1020782
193 + 1020589 = 1020782
199 + 1020583 = 1020782
241 + 1020541 = 1020782

Showing the first eight; more decompositions exist.
