Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057440, here are decompositions:

19 + 1057421 = 1057440
29 + 1057411 = 1057440
47 + 1057393 = 1057440
53 + 1057387 = 1057440
73 + 1057367 = 1057440
79 + 1057361 = 1057440
149 + 1057291 = 1057440
191 + 1057249 = 1057440

Showing the first eight; more decompositions exist.
