Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048900, here are decompositions:

3 + 1048897 = 1048900
11 + 1048889 = 1048900
23 + 1048877 = 1048900
53 + 1048847 = 1048900
71 + 1048829 = 1048900
101 + 1048799 = 1048900
107 + 1048793 = 1048900
179 + 1048721 = 1048900

Showing the first eight; more decompositions exist.
