Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639504, here are decompositions:

43 + 8639461 = 8639504
61 + 8639443 = 8639504
103 + 8639401 = 8639504
157 + 8639347 = 8639504
241 + 8639263 = 8639504
277 + 8639227 = 8639504
373 + 8639131 = 8639504
397 + 8639107 = 8639504

Showing the first eight; more decompositions exist.
