Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030440, here are decompositions:

11 + 1030429 = 1030440
23 + 1030417 = 1030440
29 + 1030411 = 1030440
71 + 1030369 = 1030440
79 + 1030361 = 1030440
83 + 1030357 = 1030440
149 + 1030291 = 1030440
193 + 1030247 = 1030440

Showing the first eight; more decompositions exist.
