Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39170, here are decompositions:

7 + 39163 = 39170
13 + 39157 = 39170
31 + 39139 = 39170
37 + 39133 = 39170
67 + 39103 = 39170
73 + 39097 = 39170
127 + 39043 = 39170
151 + 39019 = 39170

Showing the first eight; more decompositions exist.
