Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33186, here are decompositions:

5 + 33181 = 33186
7 + 33179 = 33186
37 + 33149 = 33186
67 + 33119 = 33186
73 + 33113 = 33186
79 + 33107 = 33186
103 + 33083 = 33186
113 + 33073 = 33186

Showing the first eight; more decompositions exist.
