Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697320, here are decompositions:

7 + 8697313 = 8697320
19 + 8697301 = 8697320
43 + 8697277 = 8697320
67 + 8697253 = 8697320
157 + 8697163 = 8697320
193 + 8697127 = 8697320
223 + 8697097 = 8697320
271 + 8697049 = 8697320

Showing the first eight; more decompositions exist.
