Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639948, here are decompositions:

139 + 8639809 = 8639948
151 + 8639797 = 8639948
199 + 8639749 = 8639948
349 + 8639599 = 8639948
397 + 8639551 = 8639948
409 + 8639539 = 8639948
487 + 8639461 = 8639948
547 + 8639401 = 8639948

Showing the first eight; more decompositions exist.
