Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740866, here are decompositions:

7 + 8740859 = 8740866
59 + 8740807 = 8740866
67 + 8740799 = 8740866
73 + 8740793 = 8740866
83 + 8740783 = 8740866
103 + 8740763 = 8740866
109 + 8740757 = 8740866
139 + 8740727 = 8740866

Showing the first eight; more decompositions exist.
