Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660028, here are decompositions:

29 + 8659999 = 8660028
31 + 8659997 = 8660028
71 + 8659957 = 8660028
79 + 8659949 = 8660028
89 + 8659939 = 8660028
101 + 8659927 = 8660028
107 + 8659921 = 8660028
191 + 8659837 = 8660028

Showing the first eight; more decompositions exist.
