Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668694, here are decompositions:

7 + 8668687 = 8668694
193 + 8668501 = 8668694
211 + 8668483 = 8668694
271 + 8668423 = 8668694
313 + 8668381 = 8668694
337 + 8668357 = 8668694
421 + 8668273 = 8668694
487 + 8668207 = 8668694

Showing the first eight; more decompositions exist.
