Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608986, here are decompositions:

13 + 8608973 = 8608986
73 + 8608913 = 8608986
79 + 8608907 = 8608986
97 + 8608889 = 8608986
107 + 8608879 = 8608986
149 + 8608837 = 8608986
157 + 8608829 = 8608986
163 + 8608823 = 8608986

Showing the first eight; more decompositions exist.
