Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738166, here are decompositions:

5 + 8738161 = 8738166
37 + 8738129 = 8738166
43 + 8738123 = 8738166
79 + 8738087 = 8738166
83 + 8738083 = 8738166
113 + 8738053 = 8738166
223 + 8737943 = 8738166
233 + 8737933 = 8738166

Showing the first eight; more decompositions exist.
