Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002808, here are decompositions:

11 + 1002797 = 1002808
41 + 1002767 = 1002808
89 + 1002719 = 1002808
239 + 1002569 = 1002808
281 + 1002527 = 1002808
431 + 1002377 = 1002808
449 + 1002359 = 1002808
461 + 1002347 = 1002808

Showing the first eight; more decompositions exist.
