Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718876, here are decompositions:

7 + 8718869 = 8718876
17 + 8718859 = 8718876
37 + 8718839 = 8718876
43 + 8718833 = 8718876
53 + 8718823 = 8718876
73 + 8718803 = 8718876
79 + 8718797 = 8718876
83 + 8718793 = 8718876

Showing the first eight; more decompositions exist.
