Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027808, here are decompositions:

31 + 1027777 = 1027808
211 + 1027597 = 1027808
241 + 1027567 = 1027808
337 + 1027471 = 1027808
349 + 1027459 = 1027808
487 + 1027321 = 1027808
547 + 1027261 = 1027808
601 + 1027207 = 1027808

Showing the first eight; more decompositions exist.
