Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023440, here are decompositions:

31 + 1023409 = 1023440
73 + 1023367 = 1023440
79 + 1023361 = 1023440
127 + 1023313 = 1023440
139 + 1023301 = 1023440
151 + 1023289 = 1023440
163 + 1023277 = 1023440
181 + 1023259 = 1023440

Showing the first eight; more decompositions exist.
