Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639468, here are decompositions:

7 + 8639461 = 8639468
67 + 8639401 = 8639468
241 + 8639227 = 8639468
307 + 8639161 = 8639468
337 + 8639131 = 8639468
349 + 8639119 = 8639468
379 + 8639089 = 8639468
457 + 8639011 = 8639468

Showing the first eight; more decompositions exist.
