Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021208, here are decompositions:

79 + 1021129 = 1021208
127 + 1021081 = 1021208
211 + 1020997 = 1021208
229 + 1020979 = 1021208
241 + 1020967 = 1021208
277 + 1020931 = 1021208
367 + 1020841 = 1021208
457 + 1020751 = 1021208

Showing the first eight; more decompositions exist.
