Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717678, here are decompositions:

127 + 8717551 = 8717678
157 + 8717521 = 8717678
337 + 8717341 = 8717678
349 + 8717329 = 8717678
439 + 8717239 = 8717678
547 + 8717131 = 8717678
787 + 8716891 = 8717678
859 + 8716819 = 8717678

Showing the first eight; more decompositions exist.
