Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746866, here are decompositions:

5 + 8746861 = 8746866
17 + 8746849 = 8746866
19 + 8746847 = 8746866
47 + 8746819 = 8746866
53 + 8746813 = 8746866
59 + 8746807 = 8746866
67 + 8746799 = 8746866
109 + 8746757 = 8746866

Showing the first eight; more decompositions exist.
