Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1046840, here are decompositions:

7 + 1046833 = 1046840
13 + 1046827 = 1046840
43 + 1046797 = 1046840
61 + 1046779 = 1046840
139 + 1046701 = 1046840
163 + 1046677 = 1046840
181 + 1046659 = 1046840
199 + 1046641 = 1046840

Showing the first eight; more decompositions exist.
