Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049900, here are decompositions:

3 + 1049897 = 1049900
37 + 1049863 = 1049900
43 + 1049857 = 1049900
67 + 1049833 = 1049900
73 + 1049827 = 1049900
79 + 1049821 = 1049900
109 + 1049791 = 1049900
127 + 1049773 = 1049900

Showing the first eight; more decompositions exist.
