Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028480, here are decompositions:

7 + 1028473 = 1028480
43 + 1028437 = 1028480
151 + 1028329 = 1028480
163 + 1028317 = 1028480
331 + 1028149 = 1028480
367 + 1028113 = 1028480
373 + 1028107 = 1028480
379 + 1028101 = 1028480

Showing the first eight; more decompositions exist.
