Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660928, here are decompositions:

7 + 8660921 = 8660928
19 + 8660909 = 8660928
37 + 8660891 = 8660928
41 + 8660887 = 8660928
109 + 8660819 = 8660928
131 + 8660797 = 8660928
181 + 8660747 = 8660928
229 + 8660699 = 8660928

Showing the first eight; more decompositions exist.
