Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021250, here are decompositions:

7 + 1021243 = 1021250
67 + 1021183 = 1021250
127 + 1021123 = 1021250
157 + 1021093 = 1021250
163 + 1021087 = 1021250
271 + 1020979 = 1021250
277 + 1020973 = 1021250
283 + 1020967 = 1021250

Showing the first eight; more decompositions exist.
