Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047520, here are decompositions:

29 + 1047491 = 1047520
41 + 1047479 = 1047520
53 + 1047467 = 1047520
101 + 1047419 = 1047520
179 + 1047341 = 1047520
197 + 1047323 = 1047520
239 + 1047281 = 1047520
281 + 1047239 = 1047520

Showing the first eight; more decompositions exist.
