Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025090, here are decompositions:

43 + 1025047 = 1025090
61 + 1025029 = 1025090
103 + 1024987 = 1025090
127 + 1024963 = 1025090
139 + 1024951 = 1025090
151 + 1024939 = 1025090
181 + 1024909 = 1025090
307 + 1024783 = 1025090

Showing the first eight; more decompositions exist.
