Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102170, here are decompositions:

31 + 102139 = 102170
67 + 102103 = 102170
109 + 102061 = 102170
127 + 102043 = 102170
139 + 102031 = 102170
151 + 102019 = 102170
157 + 102013 = 102170
193 + 101977 = 102170

Showing the first eight; more decompositions exist.
