Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020868, here are decompositions:

29 + 1020839 = 1020868
41 + 1020827 = 1020868
47 + 1020821 = 1020868
71 + 1020797 = 1020868
89 + 1020779 = 1020868
179 + 1020689 = 1020868
269 + 1020599 = 1020868
311 + 1020557 = 1020868

Showing the first eight; more decompositions exist.
