Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029800, here are decompositions:

43 + 1029757 = 1029800
103 + 1029697 = 1029800
157 + 1029643 = 1029800
199 + 1029601 = 1029800
223 + 1029577 = 1029800
283 + 1029517 = 1029800
313 + 1029487 = 1029800
367 + 1029433 = 1029800

Showing the first eight; more decompositions exist.
