Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698878, here are decompositions:

7 + 8698871 = 8698878
17 + 8698861 = 8698878
37 + 8698841 = 8698878
47 + 8698831 = 8698878
59 + 8698819 = 8698878
101 + 8698777 = 8698878
151 + 8698727 = 8698878
179 + 8698699 = 8698878

Showing the first eight; more decompositions exist.
