Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718888, here are decompositions:

7 + 8718881 = 8718888
11 + 8718877 = 8718888
19 + 8718869 = 8718888
29 + 8718859 = 8718888
37 + 8718851 = 8718888
89 + 8718799 = 8718888
109 + 8718779 = 8718888
131 + 8718757 = 8718888

Showing the first eight; more decompositions exist.
