Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002800, here are decompositions:

3 + 1002797 = 1002800
13 + 1002787 = 1002800
31 + 1002769 = 1002800
61 + 1002739 = 1002800
79 + 1002721 = 1002800
181 + 1002619 = 1002800
223 + 1002577 = 1002800
277 + 1002523 = 1002800

Showing the first eight; more decompositions exist.
