Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758986, here are decompositions:

7 + 8758979 = 8758986
53 + 8758933 = 8758986
83 + 8758903 = 8758986
97 + 8758889 = 8758986
107 + 8758879 = 8758986
109 + 8758877 = 8758986
139 + 8758847 = 8758986
163 + 8758823 = 8758986

Showing the first eight; more decompositions exist.
