Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025162, here are decompositions:

13 + 1025149 = 1025162
43 + 1025119 = 1025162
199 + 1024963 = 1025162
211 + 1024951 = 1025162
223 + 1024939 = 1025162
241 + 1024921 = 1025162
379 + 1024783 = 1025162
433 + 1024729 = 1025162

Showing the first eight; more decompositions exist.
