Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618264, here are decompositions:

7 + 8618257 = 8618264
13 + 8618251 = 8618264
43 + 8618221 = 8618264
157 + 8618107 = 8618264
181 + 8618083 = 8618264
223 + 8618041 = 8618264
271 + 8617993 = 8618264
331 + 8617933 = 8618264

Showing the first eight; more decompositions exist.
