Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025150, here are decompositions:

3 + 1025147 = 1025150
13 + 1025137 = 1025150
31 + 1025119 = 1025150
37 + 1025113 = 1025150
103 + 1025047 = 1025150
163 + 1024987 = 1025150
193 + 1024957 = 1025150
199 + 1024951 = 1025150

Showing the first eight; more decompositions exist.
