Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020878, here are decompositions:

31 + 1020847 = 1020878
37 + 1020841 = 1020878
127 + 1020751 = 1020878
211 + 1020667 = 1020878
337 + 1020541 = 1020878
349 + 1020529 = 1020878
421 + 1020457 = 1020878
499 + 1020379 = 1020878

Showing the first eight; more decompositions exist.
