Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740398, here are decompositions:

5 + 8740393 = 8740398
11 + 8740387 = 8740398
31 + 8740367 = 8740398
61 + 8740337 = 8740398
67 + 8740331 = 8740398
71 + 8740327 = 8740398
97 + 8740301 = 8740398
109 + 8740289 = 8740398

Showing the first eight; more decompositions exist.
