Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030390, here are decompositions:

29 + 1030361 = 1030390
41 + 1030349 = 1030390
83 + 1030307 = 1030390
149 + 1030241 = 1030390
233 + 1030157 = 1030390
269 + 1030121 = 1030390
359 + 1030031 = 1030390
401 + 1029989 = 1030390

Showing the first eight; more decompositions exist.
