Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042880, here are decompositions:

19 + 1042861 = 1042880
31 + 1042849 = 1042880
43 + 1042837 = 1042880
61 + 1042819 = 1042880
193 + 1042687 = 1042880
199 + 1042681 = 1042880
271 + 1042609 = 1042880
283 + 1042597 = 1042880

Showing the first eight; more decompositions exist.
