Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043940, here are decompositions:

11 + 1043929 = 1043940
17 + 1043923 = 1043940
19 + 1043921 = 1043940
41 + 1043899 = 1043940
43 + 1043897 = 1043940
67 + 1043873 = 1043940
71 + 1043869 = 1043940
83 + 1043857 = 1043940

Showing the first eight; more decompositions exist.
