Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006920, here are decompositions:

23 + 1006897 = 1006920
29 + 1006891 = 1006920
37 + 1006883 = 1006920
41 + 1006879 = 1006920
43 + 1006877 = 1006920
59 + 1006861 = 1006920
67 + 1006853 = 1006920
73 + 1006847 = 1006920

Showing the first eight; more decompositions exist.
