Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639894, here are decompositions:

31 + 8639863 = 8639894
97 + 8639797 = 8639894
181 + 8639713 = 8639894
331 + 8639563 = 8639894
433 + 8639461 = 8639894
547 + 8639347 = 8639894
631 + 8639263 = 8639894
643 + 8639251 = 8639894

Showing the first eight; more decompositions exist.
