Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740836, here are decompositions:

29 + 8740807 = 8740836
37 + 8740799 = 8740836
43 + 8740793 = 8740836
47 + 8740789 = 8740836
53 + 8740783 = 8740836
73 + 8740763 = 8740836
79 + 8740757 = 8740836
109 + 8740727 = 8740836

Showing the first eight; more decompositions exist.
