Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647264, here are decompositions:

11 + 8647253 = 8647264
71 + 8647193 = 8647264
83 + 8647181 = 8647264
107 + 8647157 = 8647264
137 + 8647127 = 8647264
173 + 8647091 = 8647264
233 + 8647031 = 8647264
257 + 8647007 = 8647264

Showing the first eight; more decompositions exist.
