Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025250, here are decompositions:

11 + 1025239 = 1025250
19 + 1025231 = 1025250
41 + 1025209 = 1025250
47 + 1025203 = 1025250
53 + 1025197 = 1025250
89 + 1025161 = 1025250
97 + 1025153 = 1025250
101 + 1025149 = 1025250

Showing the first eight; more decompositions exist.
