Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048880, here are decompositions:

3 + 1048877 = 1048880
13 + 1048867 = 1048880
43 + 1048837 = 1048880
73 + 1048807 = 1048880
97 + 1048783 = 1048880
163 + 1048717 = 1048880
199 + 1048681 = 1048880
271 + 1048609 = 1048880

Showing the first eight; more decompositions exist.
