Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651504, here are decompositions:

3 + 8651501 = 8651504
61 + 8651443 = 8651504
67 + 8651437 = 8651504
151 + 8651353 = 8651504
181 + 8651323 = 8651504
193 + 8651311 = 8651504
223 + 8651281 = 8651504
271 + 8651233 = 8651504

Showing the first eight; more decompositions exist.
