Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042900, here are decompositions:

3 + 1042897 = 1042900
71 + 1042829 = 1042900
101 + 1042799 = 1042900
167 + 1042733 = 1042900
191 + 1042709 = 1042900
197 + 1042703 = 1042900
269 + 1042631 = 1042900
281 + 1042619 = 1042900

Showing the first eight; more decompositions exist.
