Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718384, here are decompositions:

7 + 8718377 = 8718384
41 + 8718343 = 8718384
71 + 8718313 = 8718384
83 + 8718301 = 8718384
107 + 8718277 = 8718384
113 + 8718271 = 8718384
137 + 8718247 = 8718384
163 + 8718221 = 8718384

Showing the first eight; more decompositions exist.
