Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043872, here are decompositions:

3 + 1043869 = 1043872
23 + 1043849 = 1043872
29 + 1043843 = 1043872
41 + 1043831 = 1043872
113 + 1043759 = 1043872
149 + 1043723 = 1043872
233 + 1043639 = 1043872
281 + 1043591 = 1043872

Showing the first eight; more decompositions exist.
