Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660138, here are decompositions:

31 + 8660107 = 8660138
61 + 8660077 = 8660138
139 + 8659999 = 8660138
181 + 8659957 = 8660138
199 + 8659939 = 8660138
211 + 8659927 = 8660138
229 + 8659909 = 8660138
271 + 8659867 = 8660138

Showing the first eight; more decompositions exist.
