Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042028, here are decompositions:

7 + 1042021 = 1042028
37 + 1041991 = 1042028
67 + 1041961 = 1042028
79 + 1041949 = 1042028
109 + 1041919 = 1042028
139 + 1041889 = 1042028
199 + 1041829 = 1042028
241 + 1041787 = 1042028

Showing the first eight; more decompositions exist.
