Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740840, here are decompositions:

41 + 8740799 = 8740840
47 + 8740793 = 8740840
83 + 8740757 = 8740840
113 + 8740727 = 8740840
191 + 8740649 = 8740840
197 + 8740643 = 8740840
233 + 8740607 = 8740840
263 + 8740577 = 8740840

Showing the first eight; more decompositions exist.
