Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055900, here are decompositions:

3 + 1055897 = 1055900
7 + 1055893 = 1055900
19 + 1055881 = 1055900
37 + 1055863 = 1055900
61 + 1055839 = 1055900
73 + 1055827 = 1055900
163 + 1055737 = 1055900
211 + 1055689 = 1055900

Showing the first eight; more decompositions exist.
