Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003440, here are decompositions:

7 + 1003433 = 1003440
23 + 1003417 = 1003440
29 + 1003411 = 1003440
43 + 1003397 = 1003440
59 + 1003381 = 1003440
71 + 1003369 = 1003440
73 + 1003367 = 1003440
79 + 1003361 = 1003440

Showing the first eight; more decompositions exist.
