Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029872, here are decompositions:

13 + 1029859 = 1029872
31 + 1029841 = 1029872
229 + 1029643 = 1029872
271 + 1029601 = 1029872
373 + 1029499 = 1029872
439 + 1029433 = 1029872
463 + 1029409 = 1029872
523 + 1029349 = 1029872

Showing the first eight; more decompositions exist.
