Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043920, here are decompositions:

23 + 1043897 = 1043920
47 + 1043873 = 1043920
71 + 1043849 = 1043920
83 + 1043837 = 1043920
89 + 1043831 = 1043920
167 + 1043753 = 1043920
173 + 1043747 = 1043920
197 + 1043723 = 1043920

Showing the first eight; more decompositions exist.
