Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020906, here are decompositions:

13 + 1020893 = 1020906
53 + 1020853 = 1020906
59 + 1020847 = 1020906
67 + 1020839 = 1020906
79 + 1020827 = 1020906
83 + 1020823 = 1020906
109 + 1020797 = 1020906
127 + 1020779 = 1020906

Showing the first eight; more decompositions exist.
