Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718568, here are decompositions:

29 + 8718539 = 8718568
107 + 8718461 = 8718568
137 + 8718431 = 8718568
149 + 8718419 = 8718568
167 + 8718401 = 8718568
191 + 8718377 = 8718568
317 + 8718251 = 8718568
347 + 8718221 = 8718568

Showing the first eight; more decompositions exist.
