Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025210, here are decompositions:

7 + 1025203 = 1025210
13 + 1025197 = 1025210
61 + 1025149 = 1025210
73 + 1025137 = 1025210
97 + 1025113 = 1025210
163 + 1025047 = 1025210
181 + 1025029 = 1025210
223 + 1024987 = 1025210

Showing the first eight; more decompositions exist.
