Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016900, here are decompositions:

19 + 1016881 = 1016900
61 + 1016839 = 1016900
127 + 1016773 = 1016900
151 + 1016749 = 1016900
163 + 1016737 = 1016900
211 + 1016689 = 1016900
331 + 1016569 = 1016900
373 + 1016527 = 1016900

Showing the first eight; more decompositions exist.
