Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747264, here are decompositions:

3 + 8747261 = 8747264
7 + 8747257 = 8747264
13 + 8747251 = 8747264
73 + 8747191 = 8747264
181 + 8747083 = 8747264
193 + 8747071 = 8747264
223 + 8747041 = 8747264
307 + 8746957 = 8747264

Showing the first eight; more decompositions exist.
