Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026250, here are decompositions:

23 + 1026227 = 1026250
53 + 1026197 = 1026250
83 + 1026167 = 1026250
107 + 1026143 = 1026250
131 + 1026119 = 1026250
149 + 1026101 = 1026250
293 + 1025957 = 1026250
311 + 1025939 = 1026250

Showing the first eight; more decompositions exist.
