Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016920, here are decompositions:

11 + 1016909 = 1016920
29 + 1016891 = 1016920
41 + 1016879 = 1016920
71 + 1016849 = 1016920
131 + 1016789 = 1016920
137 + 1016783 = 1016920
239 + 1016681 = 1016920
257 + 1016663 = 1016920

Showing the first eight; more decompositions exist.
