Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639396, here are decompositions:

97 + 8639299 = 8639396
277 + 8639119 = 8639396
307 + 8639089 = 8639396
397 + 8638999 = 8639396
463 + 8638933 = 8639396
487 + 8638909 = 8639396
547 + 8638849 = 8639396
709 + 8638687 = 8639396

Showing the first eight; more decompositions exist.
