Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651264, here are decompositions:

3 + 8651261 = 8651264
31 + 8651233 = 8651264
73 + 8651191 = 8651264
103 + 8651161 = 8651264
283 + 8650981 = 8651264
337 + 8650927 = 8651264
367 + 8650897 = 8651264
487 + 8650777 = 8651264

Showing the first eight; more decompositions exist.
