Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651678, here are decompositions:

31 + 8651647 = 8651678
97 + 8651581 = 8651678
241 + 8651437 = 8651678
349 + 8651329 = 8651678
367 + 8651311 = 8651678
397 + 8651281 = 8651678
439 + 8651239 = 8651678
487 + 8651191 = 8651678

Showing the first eight; more decompositions exist.
