Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026880, here are decompositions:

47 + 1026833 = 1026880
89 + 1026791 = 1026880
293 + 1026587 = 1026880
317 + 1026563 = 1026880
359 + 1026521 = 1026880
401 + 1026479 = 1026880
431 + 1026449 = 1026880
467 + 1026413 = 1026880

Showing the first eight; more decompositions exist.
