Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049880, here are decompositions:

17 + 1049863 = 1049880
19 + 1049861 = 1049880
23 + 1049857 = 1049880
31 + 1049849 = 1049880
37 + 1049843 = 1049880
43 + 1049837 = 1049880
47 + 1049833 = 1049880
53 + 1049827 = 1049880

Showing the first eight; more decompositions exist.
