Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021300, here are decompositions:

3 + 1021297 = 1021300
11 + 1021289 = 1021300
17 + 1021283 = 1021300
29 + 1021271 = 1021300
41 + 1021259 = 1021300
47 + 1021253 = 1021300
83 + 1021217 = 1021300
101 + 1021199 = 1021300

Showing the first eight; more decompositions exist.
