Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66106, here are decompositions:

3 + 66103 = 66106
17 + 66089 = 66106
23 + 66083 = 66106
59 + 66047 = 66106
113 + 65993 = 66106
149 + 65957 = 66106
179 + 65927 = 66106
239 + 65867 = 66106

Showing the first eight; more decompositions exist.
