Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639318, here are decompositions:

19 + 8639299 = 8639318
67 + 8639251 = 8639318
157 + 8639161 = 8639318
199 + 8639119 = 8639318
211 + 8639107 = 8639318
229 + 8639089 = 8639318
307 + 8639011 = 8639318
367 + 8638951 = 8639318

Showing the first eight; more decompositions exist.
