Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009920, here are decompositions:

11 + 1009909 = 1009920
19 + 1009901 = 1009920
47 + 1009873 = 1009920
61 + 1009859 = 1009920
83 + 1009837 = 1009920
101 + 1009819 = 1009920
113 + 1009807 = 1009920
139 + 1009781 = 1009920

Showing the first eight; more decompositions exist.
