Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740740, here are decompositions:

13 + 8740727 = 8740740
59 + 8740681 = 8740740
61 + 8740679 = 8740740
83 + 8740657 = 8740740
97 + 8740643 = 8740740
137 + 8740603 = 8740740
149 + 8740591 = 8740740
163 + 8740577 = 8740740

Showing the first eight; more decompositions exist.
