Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029808, here are decompositions:

5 + 1029803 = 1029808
41 + 1029767 = 1029808
191 + 1029617 = 1029808
239 + 1029569 = 1029808
281 + 1029527 = 1029808
401 + 1029407 = 1029808
449 + 1029359 = 1029808
467 + 1029341 = 1029808

Showing the first eight; more decompositions exist.
