Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758864, here are decompositions:

3 + 8758861 = 8758864
17 + 8758847 = 8758864
41 + 8758823 = 8758864
71 + 8758793 = 8758864
83 + 8758781 = 8758864
131 + 8758733 = 8758864
167 + 8758697 = 8758864
227 + 8758637 = 8758864

Showing the first eight; more decompositions exist.
