Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017900, here are decompositions:

11 + 1017889 = 1017900
19 + 1017881 = 1017900
41 + 1017859 = 1017900
43 + 1017857 = 1017900
53 + 1017847 = 1017900
73 + 1017827 = 1017900
83 + 1017817 = 1017900
101 + 1017799 = 1017900

Showing the first eight; more decompositions exist.
