Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025028, here are decompositions:

7 + 1025021 = 1025028
19 + 1025009 = 1025028
31 + 1024997 = 1025028
41 + 1024987 = 1025028
71 + 1024957 = 1025028
89 + 1024939 = 1025028
97 + 1024931 = 1025028
107 + 1024921 = 1025028

Showing the first eight; more decompositions exist.
