Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029900, here are decompositions:

17 + 1029883 = 1029900
19 + 1029881 = 1029900
41 + 1029859 = 1029900
59 + 1029841 = 1029900
61 + 1029839 = 1029900
73 + 1029827 = 1029900
97 + 1029803 = 1029900
149 + 1029751 = 1029900

Showing the first eight; more decompositions exist.
