Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041840, here are decompositions:

11 + 1041829 = 1041840
17 + 1041823 = 1041840
47 + 1041793 = 1041840
53 + 1041787 = 1041840
61 + 1041779 = 1041840
83 + 1041757 = 1041840
103 + 1041737 = 1041840
109 + 1041731 = 1041840

Showing the first eight; more decompositions exist.
