Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1053440, here are decompositions:

19 + 1053421 = 1053440
79 + 1053361 = 1053440
139 + 1053301 = 1053440
181 + 1053259 = 1053440
337 + 1053103 = 1053440
373 + 1053067 = 1053440
379 + 1053061 = 1053440
433 + 1053007 = 1053440

Showing the first eight; more decompositions exist.
