Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045806, here are decompositions:

5 + 1045801 = 1045806
7 + 1045799 = 1045806
43 + 1045763 = 1045806
67 + 1045739 = 1045806
79 + 1045727 = 1045806
127 + 1045679 = 1045806
163 + 1045643 = 1045806
173 + 1045633 = 1045806

Showing the first eight; more decompositions exist.
