Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639528, here are decompositions:

67 + 8639461 = 8639528
127 + 8639401 = 8639528
181 + 8639347 = 8639528
229 + 8639299 = 8639528
277 + 8639251 = 8639528
367 + 8639161 = 8639528
379 + 8639149 = 8639528
397 + 8639131 = 8639528

Showing the first eight; more decompositions exist.
