Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649272, here are decompositions:

19 + 8649253 = 8649272
31 + 8649241 = 8649272
61 + 8649211 = 8649272
193 + 8649079 = 8649272
211 + 8649061 = 8649272
223 + 8649049 = 8649272
271 + 8649001 = 8649272
349 + 8648923 = 8649272

Showing the first eight; more decompositions exist.
