Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639654, here are decompositions:

7 + 8639647 = 8639654
103 + 8639551 = 8639654
193 + 8639461 = 8639654
211 + 8639443 = 8639654
241 + 8639413 = 8639654
307 + 8639347 = 8639654
523 + 8639131 = 8639654
547 + 8639107 = 8639654

Showing the first eight; more decompositions exist.
