Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043440, here are decompositions:

71 + 1043369 = 1043440
89 + 1043351 = 1043440
149 + 1043291 = 1043440
227 + 1043213 = 1043440
239 + 1043201 = 1043440
257 + 1043183 = 1043440
263 + 1043177 = 1043440
443 + 1042997 = 1043440

Showing the first eight; more decompositions exist.
