Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740686, here are decompositions:

5 + 8740681 = 8740686
7 + 8740679 = 8740686
29 + 8740657 = 8740686
37 + 8740649 = 8740686
43 + 8740643 = 8740686
79 + 8740607 = 8740686
83 + 8740603 = 8740686
107 + 8740579 = 8740686

Showing the first eight; more decompositions exist.
