Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740540, here are decompositions:

23 + 8740517 = 8740540
47 + 8740493 = 8740540
113 + 8740427 = 8740540
167 + 8740373 = 8740540
173 + 8740367 = 8740540
239 + 8740301 = 8740540
251 + 8740289 = 8740540
353 + 8740187 = 8740540

Showing the first eight; more decompositions exist.
