Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025208, here are decompositions:

5 + 1025203 = 1025208
11 + 1025197 = 1025208
47 + 1025161 = 1025208
59 + 1025149 = 1025208
61 + 1025147 = 1025208
71 + 1025137 = 1025208
89 + 1025119 = 1025208
97 + 1025111 = 1025208

Showing the first eight; more decompositions exist.
