Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047808, here are decompositions:

29 + 1047779 = 1047808
71 + 1047737 = 1047808
107 + 1047701 = 1047808
137 + 1047671 = 1047808
257 + 1047551 = 1047808
269 + 1047539 = 1047808
317 + 1047491 = 1047808
389 + 1047419 = 1047808

Showing the first eight; more decompositions exist.
