Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66108, here are decompositions:

5 + 66103 = 66108
19 + 66089 = 66108
37 + 66071 = 66108
41 + 66067 = 66108
61 + 66047 = 66108
67 + 66041 = 66108
71 + 66037 = 66108
79 + 66029 = 66108

Showing the first eight; more decompositions exist.
