Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013806, here are decompositions:

89 + 1013717 = 1013806
107 + 1013699 = 1013806
179 + 1013627 = 1013806
197 + 1013609 = 1013806
557 + 1013249 = 1013806
569 + 1013237 = 1013806
653 + 1013153 = 1013806
743 + 1013063 = 1013806

Showing the first eight; more decompositions exist.
