Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758866, here are decompositions:

5 + 8758861 = 8758866
19 + 8758847 = 8758866
43 + 8758823 = 8758866
47 + 8758819 = 8758866
73 + 8758793 = 8758866
79 + 8758787 = 8758866
89 + 8758777 = 8758866
197 + 8758669 = 8758866

Showing the first eight; more decompositions exist.
