Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740406, here are decompositions:

13 + 8740393 = 8740406
19 + 8740387 = 8740406
79 + 8740327 = 8740406
223 + 8740183 = 8740406
277 + 8740129 = 8740406
439 + 8739967 = 8740406
487 + 8739919 = 8740406
523 + 8739883 = 8740406

Showing the first eight; more decompositions exist.
