Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65166, here are decompositions:

19 + 65147 = 65166
37 + 65129 = 65166
43 + 65123 = 65166
47 + 65119 = 65166
67 + 65099 = 65166
103 + 65063 = 65166
113 + 65053 = 65166
137 + 65029 = 65166

Showing the first eight; more decompositions exist.
