Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740806, here are decompositions:

7 + 8740799 = 8740806
13 + 8740793 = 8740806
17 + 8740789 = 8740806
23 + 8740783 = 8740806
43 + 8740763 = 8740806
79 + 8740727 = 8740806
127 + 8740679 = 8740806
149 + 8740657 = 8740806

Showing the first eight; more decompositions exist.
