Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651564, here are decompositions:

127 + 8651437 = 8651564
211 + 8651353 = 8651564
241 + 8651323 = 8651564
283 + 8651281 = 8651564
331 + 8651233 = 8651564
373 + 8651191 = 8651564
421 + 8651143 = 8651564
547 + 8651017 = 8651564

Showing the first eight; more decompositions exist.
