Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021836, here are decompositions:

5 + 1021831 = 1021836
29 + 1021807 = 1021836
37 + 1021799 = 1021836
43 + 1021793 = 1021836
59 + 1021777 = 1021836
83 + 1021753 = 1021836
89 + 1021747 = 1021836
139 + 1021697 = 1021836

Showing the first eight; more decompositions exist.
